Sometimes, when connecting a flash drive, printer or other devices that connect via USB, an error occurs, that the USB device is not recognized. This problem relevant, both in Windows 7 and Windows 8, and in Windows 10. Also, this error occurs when working with USB 2.0 and USB 3.0. Therefore, today we will write simple instructions with several methods to solve this problem. Go.
What to do if "USB device not recognized"
So, if a similar error occurs when connecting any device via USB, then first of all you need to connect it to another USB port y. The problem may be just in the device itself and we need to make sure of this.
Further, if the computer does not see the device through other ports, then you need to test it on another computer or laptop. If the device is still not recognized by the computer, then the problem is most likely in the device itself. In this case, it is necessary to diagnose the device itself. By the way, if everything is as described just above, then the methods described below are unlikely to help you. At best, read on.
There is another way after which it is more likely that the USB device will work:
- To begin, remove the device itself from USB input, then turn off the computer and remove the plug from the socket, now press the power button and HOLD for a few seconds. Thus, the remaining charge will disappear from other components.
- Turn on the computer and try to connect the USB device. Most likely it will work.
The third method is a little faster than the previous ones. It lies in the fact that if the computer, in USB ports, connected a lot various devices, then you should try to disable some of them, and connect the non-recognizing device to the rear USB output. If everything worked, then congratulations, otherwise go to the next step.
We solve the problem through the device manager
In this method, we will use the task manager and I immediately want to notice that this method will help someone, but not someone. So, for starters, by pressing the keys Win+R, open the window Run"And enter a phrase there that will open the device manager for us: devmgmt.msc.
Since, today we are talking about problems with USB, then most likely the problematic device is in the section " USB controllers". There are also unidentified devices that you should also pay attention to.
If the device is unidentified, that is, with a yellow exclamation mark, then you can try to update it via the Internet by clicking on it PKM. Or, if that doesn't work, use online version Driver Pack Solution, which will help you find the missing driver. We wrote about her.
And here are a couple more methods, in case an unidentified device is located in the USB controllers tab.
- Click on the RMB device and in " properties» select the tab « Driver where you need to click roll back. If there is no such item, then just click delete, and then update the hardware configuration and see if the unidentified device has disappeared.
- In this case, we need to go to the item " Generic USB Hub», « USB Root Controller" And " USB hub". In the properties of these devices in " power management» it is necessary to REMOVE the check mark in the item « Allow this device to turn off to save power».
The following method, which works on Windows 8.1, is that for all the devices that we have listed above, you need to properties click on the button " Update drivers”And then, in the window that appears, select the search on this computer. The most compatible ones should already be on the computer, and you will see them in the window. You need to select it and click next. If everything went well, you can try connecting a USB device that did not work. By the way, before connecting, I would advise you to restart your computer again.
Devices not recognized in Windows 8.1 - USB 3.0
For example, on laptops, this problem can be a fairly common condition. Especially if Windows 8.1 is installed, and devices such as flash drives work on USB 3.0.
To solve this same error with a non-recognizing device, you need to change some settings in . For this you need to go to Control Panel and select " Power supply". Now you need to select the power scheme that you are using, for example, " High performance", can be set for everyone. So, by clicking on Power plan settings» Next you need to go to « change Extra options… ". In the USB port temporary shutdown parameters item, you must activate the value " ban».
That's all. If this article helped you, be sure to unsubscribe about it in the comments. In the event that I have missed any other valid methods of fixing this error, it would not be bad if you also told about it in the comments.
Doesn't work properly" on its own. They know their computer down to the smallest detail, so there are no questions about how to fix this or that error. But for inexperienced users in this matter, it is much more difficult. For some, even advice from the Internet does not help, because there is too little knowledge and experience.
Problem
But that's not a problem. Any basic PC error can be resolved quickly. To do this, you need to carefully study the instructions and follow step-by-step advice from experts.
Today's problem is when one of them doesn't work properly. Most often, you will notice this text in the lower right corner of the desktop. Sometimes a special window appears with a notification about this problem.
Prerequisites
Most often, the error occurs when connecting any device via USB. This is a regular flash drive, and a phone, and a printer, etc. The problem occurs both on early version Windows 7, and later - "Ten". However, your USB may be version 2.0 or 2.0. In general, the essence of the issue does not change from this.
Causes
An error accompanied by a USB connection can be caused by a number of reasons. Indeed, there are a lot of them. And they are not always typical. It happens that the fault lies directly and completely with the user, who miraculously removed the drivers or confused the system. There are also flaws on the part of the manufacturers of these devices. Poor quality Chinese flash drives are especially prone to this problem.
Trust but check
So, you saw a similar error on your screen. In order to avoid unnecessary nerves and wasting a lot of time, it is better to immediately check the device that you connect to the port. As mentioned earlier, not all manufacturers are so conscientious. Many people create a product just to sell. This results in system errors.
If you bought a new mouse, keyboard or flash drive, immediately check that it is working properly before sinning on the USB interface. To do this, you can use two methods:
- If you have a second PC or laptop, just connect your new device to it. If everything is fine on another system, then most likely the problem is in the computer.
- Take a working device (an old mouse, a second flash drive, etc.) and insert it into the same port. If the same notification appears, then the problem is really in the connector.
There are a couple of hidden ways. They do not always give a clear picture of what is happening, but just in case, you can try them out. So, we take the device that gives an error, disconnect it from the PC and turn off the system along with the plug in the outlet. Now you need to hold down the start button on the computer so that the remnants electric charges left the motherboard.
Now turn on the PC and connect the USB device when the system boots up completely. The option is not the best, but sometimes after it everything really starts to work.
And for those who finally want to make sure that the port is malfunctioning, you can simply turn off all the USB that are on the interface panel. It happens that port overload can give a similar error. If you disable unnecessary this moment equipment, install the flash drive in the back panel.
Software methods
Sometimes the problem “One of the connected USB devices is not working properly” cannot be fixed by reshuffling alone. We'll have to dig inside the system. If all the previous methods did not give you a result, let's try to update the "firewood".
To do this, we are looking for "Device Manager". We do it through the command line: hold down Win + R on the keyboard and enter devmgmt.msc in the field. You can go to "My Computer", right-click anywhere in the window and select "Properties". A window with PC parameters will open in front of us, and in the left column you will find the desired section.
So, in the "Device Manager" select the line "USB Controllers", here all the USB equipment connected to the system is shown. There will be a line "Other devices", it is in it that our unknown device will be located. Click on its name and try "Update Drivers". We are waiting for the system itself to download via the Internet necessary files, and, perhaps, the flash drive will “come to its senses” and work.
Exclamation mark
It may be that next to this "Unknown device" is a yellow exclamation mark. In this case, we try to roll back the drivers. Click on it and go to Properties. Here you need to find a tab with "firewood" and the "Rollback" button. Perhaps it will be unavailable to you, highlighted in gray. Then select "Delete".
Now you need to return to the "Device Manager" window and select the "Action" section from the top, and update the hardware configuration in it. These steps may fix your issue.
The exclamation point may appear for another reason. To do this, you need to go to the properties of the equipment that has acquired names such as Generic USB Hub, USB Root Controller and USB Root Hub. In the window that appears, select "Power Management" and uncheck the first line. This will prevent the equipment from turning off to save electricity.
Common Mistakes and Solutions
As mentioned earlier, the error “One of the connected USB devices is not working properly” is individual and depends on many factors. We have covered the most common causes above. And now let's briefly try to describe what kind of malfunctions other users encountered.
Often this error occurs when connecting a printer. Usually caused by incorrect installation of "firewood". Therefore, you can simply remove them and carefully reinstall them again.
Many problems arise due to mechanical damage. Suppose a cable with a micro-USB connector on one side and USB on the other can be broken or crushed in the middle. It also significantly affects the performance and synchronization of it with the PC.
Another interesting problem, which is now becoming less and less common, can be incompatibility. Some devices do not support 2.0 or newer 3.0. Then it happens that by connecting through USB phone or any other device, you will see this message again. In general, if such a problem arose, then it is better to think about changing motherboard, as the interface standard will continue to change, and there will be even more problems.
Laptop problems
In this case we run into problems USB connections 3.0. Due to the imperfection of this revision of the interface, users have to get out different ways. A solution has been found. The laptop needed to adjust the power plan.
To do this, you could go to standard settings this parameter or in proprietary software, which is provided by some laptop manufacturers. In Windows, select the power plan that is currently in use, then go to advanced settings. And already according to the familiar scheme, we prohibit disabling ports to save energy.
conclusions
If suddenly you cannot connect a phone via USB, an external HDD, flash drive and other devices, you don’t need to get upset right away. First, the breakdown of one port out of ten in the system is a common thing. Trying to just use a different connector is as easy as shelling pears. Secondly, even if you didn’t succeed programmatically, you can try reinstalling Windows.
Of course, reinstalling the OS is not a panacea for all problems and the process is quite difficult, especially for those who have never encountered it. However, even he can help you.
It is possible that your micro-USB connector is not working due to a real controller failure. It cannot be replaced on the motherboard. It's either to buy new motherboard, or, alternatively, purchase an external controller with a PCI interface.
It happens that when you turn on the computer, you suddenly notice that the mouse does not respond to your movements. This can happen with both a wired USB and a wireless mouse. Usually, the reasons for this are the same type of cases and are already known to many specialists. Therefore, we will consider all the most popular reasons why the computer does not see the mouse and we will give several solutions in the article that should definitely help you.
First of all, your task is to determine whether your reasons for a non-working mouse are primitive.
Ways to solve the problem with a USB mouse
If the problem occurs with a mouse that is connected via a USB port and the computer does not see it when it is turned on:
- Disconnect the mouse USB connector from the computer panel and turn off the computer. Disconnect it from the mains and press the power button on the computer for a few seconds - this way you will completely clear the computer modules from charges, first of all, the motherboard.
- Now turn on the computer and connect the mouse after Windows startup. The mouse should work.
Now let's fix the problem with the USB mouse using. This method is appropriate when the system does not recognize such a device in the device manager of your PC. To open the Device Manager, right-click on the "My Computer" icon and select the appropriate item or through the WIN + R command line and enter the command "Devmgmt.msc" and press Enter.
You will find the device in the body of the list, it will look like "USB controllers" or "Other devices" ("Unknown device"). If it is in your list looks like an unidentified device, then you need to right-click on it and select "Update Driver". In this case, the system automatically finds required drivers and installs them without your intervention. After this installation, you can use a working mouse.
If there is an exclamation mark next to our mouse in the task manager:
Physical breakdowns due to which the computer does not see the mouse
With careless use, even the USB connector can become unusable. Check the pins on the port and in the mouse connector, they may be damaged, bent, worn out. Although the USB connector is very durable, still active use it could break, the contacts could also loosen. In this case, you need to contact the service to replace the USB ports on the motherboard or purchase a new one.
The mouse cable can also suffer from all sorts of damage that leads to a break in the wires inside the cable. There are cases when they are gnawed by domestic animals. In this case, the system will notify you with a message - "Unable to connect to the USB port" or. The USB cable has 5 cores, which are not so easy to reconnect together. This is probably the easiest place to buy a new mouse. If the model is expensive, it can be saved in the service. 
In addition to the wire, breakdowns can also occur in the mouse body itself.
The main faults inside the case:
- The lens surface is dirty, scratched.
- Buttons don't work. The arrow runs around the monitor, but click commands are not executed.
- Faulty main board, reader, photocells, etc.
- The wheel controller is defective. In this case, there is no way to scroll the pages up and down.
- Unreliable front USB ports. When several ports are connected to the board of one microcontroller. It happens that inexperienced users connect several 4G modems and printers to such ports at the same time - if a failure does not happen, then it will definitely happen. Modems will often lose cellular network and periodically terminate the connection. The same will happen with the printer, it will slow down in every possible way, stop without printing the document to the end. The USB mouse may not be recognized by the system. As you may have guessed, you need to distribute the equipment across all USB ports of the computer, including on the rear panel.
On wireless mice:
USB 3.0 laptop does not see the mouse
Laptops under control operating system 8.1 often encounter the "USB device not recognized" error. To prevent this problem? You need to change your laptop's power plan.
Mouse issues across devices and versions of Windows
After reinstalled Windows systems Chipset driver incompatibility may cause the mouse to malfunction. Each operating system includes touch, mouse, touchpad drivers, except for MS-DOS. A common cause of mouse failure is a non-working USB driver, component - "Serial Bus Controller" and "Root Hub". You need to find on the net the version of the chipset that will fit the version of Windows that you currently have installed. Although for 8.1/10 versions, the main drivers are already provided as system components, they do not need to be installed separately. 
ACER netbooks, which are provided with Windows 7 by the manufacturer, when installing versions above, a problem appeared - the mouse did not work. The problem was in the hardware of the netbook - the Windows 7 chipset drivers did not fit and the following problems arose: the wireless network connection, the sensor did not work, the mouse did not work (the pointer was in one place). The problem was solved by removing the drivers and restarting the operating system. Devices and equipment worked normally again.

USB device problems, diagnostics and solutions.
The branch is devoted to problems with flash drives initially - the definition, data recovery, recovery. But the tips given here, in the end, relate to USB devices and storage media in general.
In the title I will try to track interesting solutions and summarize the information.
Questioners are requested to first read, think and try the solutions BEFORE asking a question.So .... on the little things in the posts below there is a lot, but I'll try to sum it up, and the total result applies to almost all USB devices (let's omit the exotic about incorrectly connected USB panels to mother's consumption at once):
1. Data recovery
with a reference flash, with modern operating systems is not an issue. They are recognized by the software and processed as hards, so we forget it, okay???2. Software that can unlock flash drives, format them, etc.
and others are somewhat individual, highly dependent on the controller in the flash drive, and we will encounter the search problem a little later.3. Much can be solved
via DOS commands...and drivers. Advice from Linux experts is welcome. It's easy to find dredges for DOS .. in any search engine, type USB-DOS ... and you will find4. Quite often
flash drives locked under XP are normally formatted under 98, and then they live normally in other systems. For quiet work with most different types of devices in 98, you can use the link:
http://lemnews.com/drivers/
there are working threads...5. Non-essential addition
at the moment - the ifa is confirmed that, for example, the 98 woods are made using a single technology ... is there a native? And how to make the device see itself without a native or in case of undefined it? It's simple - using USBView to read the vID-pID of the device... and in the info-file of drives from another normally working device, correct what you are looking for to the required one. And this applies not only to flash drives, but to everything growing under USB.6. A flash drive is seen on one computer, and does not work on another.
Quite often a pop-up problem. To partially solve the problem, I recommend going to:
http://www.krn.ru/support/FAQ/Last_C...B_in_WinXP.htm
I think it will work under 2k with minor changes ...7. Is the device working?
You connect the device .. and it goes into confusion ... either it doesn’t see it, or it asks for a drive ..... What should I do? It's simple - we try to use USBView and read the info here:
http://www.krn.ru/support/UDsearch.htm
perhaps the device is simply not understood by the system normally. Solution options - find the right drive, look up the top, find the right software ..... everything is in the link ...
For work, I can throw a link to the file ID:
http://www.linux-usb.org/usb.ids
And yet ... when working with USBView, I recommend that you check the Config Deskriptors checkbox in Options so that the prog gives out more information on the connection ... it will help! And do not be lazy to click on the refresh handles ... and look for a fresher version of the program, if any!
Tips from Linux specialists and their data are welcome!
If the device is not determined by this method from a poke-joint ... that's all, read below .... and there, according to the results, either a wooden jacket and a funeral in a trash can, or to the craftsmen for soldering the controller, and along the way there are planar inductances , transformation chains and so on ... it all depends on the decency of the specialist and your facade of the muzzle ...
For example, my BUS makes current for me at cost .... well, sometimes we pick, however, about good decision this or that problem ... but this does not apply to the top !!!8. You can not read .. ..
But problems were noticed under XP and 2K with intermediate hubs-card readers. The flash drive suddenly breaks off .. only reconnect restores the connection. I see a problem in one - the interpretation of codes-data flows between the hub on the mother and the intermediate host ...
And also due to the lack of nutrition ... such hosts often feed from the mother herself ... which is not good! As an example, screws that live through unstable power adapters can suddenly, with a fright due to a power surge, either cut off or lock up .... tested in practice. This can also apply to USB devices. Think for yourself, decide for yourself....Explanations at the end of paragraph 8
Just in case, I will allow myself one more lyrical digression.
Well, this is so, for greater heights, although it is very exaggerated, but I think it is accessible.
It must be remembered that in addition to the main power supply circuits of the motherboard, there is also a very necessary reference + 5VSB.
According to the basics of power and mamostroeniya standards, it provides standby currents in the mother's standby mode, a ready-to-start signal, the start-up and feeding of peripherals that can start the computer, such as:
-mouse-clave
-setevushki-modems-like hardware with WOL \ WOR functions to wake up mom
-memory in STR mode
- quartz on the mother (clocks, timers, etc.)
- save data in CMOS
-USB-peripherals in standby mode-shutdown the computer
- well, on the little things .....
So, if we follow the canons, then we have a low-current constant reference in the form of this power branch.
And according to the same canons, after starting at a certain moment, the automation MUST switch the power supply of the periphery and others to the main +5 volts. In this case, measurements will show that after some dip further, the + 5VSB branch will be exactly 5 volts with minimal fluctuations.
Also remember that when the current threshold through this interface reaches 750 milliamps, the automation MUST also briefly turn off the interface and not turn it back on until the current consumption drops ... otherwise, kerdyk.
But ... alas, now mothers are blurting out who is in what much, so it’s not worth looking for a standard.
And now you can think for a moment what happens if the automation does not switch the power to the main source at startup. The currents may be enough for the main work, but connecting each new consumer to this power circuit will drain it ... and depending on the solution of the circuits, either the next consumer will not receive sufficient power, and as a result it simply will not be recognized ... either a jump and how a variant of BSOD or even turning off the nurse.
It is very easy to observe power references if you have a head and an oscilloscope (well, a normal probe is also good), or programs like Sensor. And the dances of this reference may indicate that either the sensor on the mother is dying, and this is very unpleasant, or we have a problem in nutrition.
A partial solution to the problem lies in reading the phages to the mothers. Quite often there was such an option - some ports with jumpers on the mother can be powered not only from the duty bus (+ 5VSB), but also from the main power circuit, which receives current after starting the computer. This is done by installing jumpers (we are looking for it in the descriptor). Sometimes, but very rarely, such switches are present in the BIOS-CMOS settings.Http://www.rdm.kiev.ua/flashutil.php utilities for usb
Surely, many of the users have already encountered a problem when, when a USB device is connected to a computer, the message “ USB device not recognized." Most often, this is observed when standard flash drives are connected to a PC, but it is not rare that this message occurs after connecting more massive devices (external hard disks, telephones, digital cameras, printers, etc.). In this article, I will analyze this problem in detail and describe how to fix the USB device not recognized error on Windows 7 and 10, what are the causes of this dysfunction.
Why does the USB device not recognized message appear on Windows
As follows from the text of the message, it indicates various problems with the USB port on your computer, or with the USB device itself that you connect to your PC.
The specific causes of the error USB device is not detected on Windows 7 and 10 may be as follows:
How to fix USB recognition error when connected
So, how to get rid of "USB Device Not Recognized"? I recommend doing the following:
- Disconnect your device from the PC, and then turn it back on after a couple of seconds. Quite often this is effective;
- Restart your computer. Disconnect the USB device, restart the PC, and then reconnect the device. If the problem is random, then it will disappear;
- Check the functionality of the connected device. Try connecting it to another PC and make sure the connection went well. If the device is not detected on another PC, then it is quite possible that it needs to be repaired;
- Disconnect other USB devices from the computer(including the USB hub through which your device connects to the PC). Sometimes simultaneous connection several USB devices to a PC can create a conflict between them (or there simply isn’t enough power to service all devices). Disconnect other USB devices, leaving only the one you need;
- Try connecting your device to a different USB port. Perhaps the specific port to which the device is connected does not work correctly (physical failure);
- Try changing the cord through which the device is connected to the PC,
- Remove the remaining charge from the PC motherboard. Disconnect your device and turn off your computer. Unplug the PC cord from the surge protector (or outlet) and press the power button of your computer, holding it down for about 5-10 seconds. Then turn on your PC again, wait for the system to boot, and then reconnect your USB device;
- Uninstall all USB controllers. Go to the "Device Manager" (click on the "Start" button, type devmgmt.msc in the search bar and press enter), open the "USB Controllers" tab there and, right-clicking on each of them, select "Delete". Remove all controllers in this way and then reboot your system. After the reboot, the system will reinstall all controllers, it is quite possible that the problem “USB Device Not Recognized” will be solved;
- Install the correct drivers for the USB device. Go to Device Manager, among the list of available devices, find your device (usually it looks like "Unknown Device" in the "Other Devices" section, or in the "USB Controllers" section, and usually with an exclamation point).
In the case when the connected device is displayed as "Unknown Device", you can try to update the drivers for it by right-clicking on it and selecting the "Update Drivers" option from the menu that appears.
- If our device is in "USB Controllers", then hover over the device, right-click and select "Properties".
- Go to the "Driver" tab and select the "Roll Back" option there (if the system has previous version driver), otherwise click on "Uninstall".
- Then click on "Action" at the top, and select the "Update hardware configuration" option there.
- The system will check the available devices, and, having found our USB device, it will try to connect it correctly and install drivers for it.
You can also sequentially enter the properties of each of the Generic USB Hub, USB Root Controller and USB Root Hub devices, and go to the "Power Management" tab, uncheck the option "Allow the computer to turn off this device to save power", and see if device to work correctly.
Conclusion
If, when you connect your USB device to your computer, you receive the message “USB device not recognized”, then I recommend that you consistently follow all the tips I listed above. I advise you to pay special attention to removing the charge from the motherboard and updating the drivers for your USB device - these tricks help in quite a few cases, helping to effectively solve the problem of recognizing USB devices.

If you have not installed Windows Hotfix Package Q810400" And "Windows Hotfix Package KB822603"- then immediately install ( http://windowsupdate.microsoft.com/) and hopefully you won't need to read any further.
The device itself WORKS. Have you checked this on another machine? .
When connected specifically to your computer, it is either not detected at all, or it is detected incorrectly, or even correctly detected, but does not work as it should.
You are sure that all the necessary drivers for all devices connected to the system are installed.
Are you sure that reinstalling and updating USB drivers controllers and USB devices are made correctly.
In "Device manager" (Device manager) - shows that all devices are working fine and there are no conflicts.
The device still does not work, nothing helps and you are ready to reinstall the system.
Reason.
As a rule, this situation can occur if the USB 2.0 Enhanced Host Controller uses one interrupt along with some other device (IRQ Sharing), such as audio or video. In this case, the correct transmission of parameters (FDO, PDO) from drivers is violated USB (usbhub.sys, usbstor.sys, usbport.sys) to drivers logical devices, for example from usbstor.sys to disk.sys in case USB 2.0 mass storage device.
Possible solutions.
NECESSARY RESERVATION:
ALL further actions You manufacture at your own risk and neither I nor our company nor any third party assumes no responsibility for the consequences of your actions. If you do not understand the meaning of the actions described below at all, it is better for you not to do this. In any case, save everything you can, make a backup, create a restore point, etc.
The following is written based on the answer " Microsoft Windows Support Professional" to Mr. rosest, which he published in the conference site http://www.experts-exchange.com/Hardware/Q_20790258.html with the permission of MS support. Although it mentions a digital camera, this applies to all USB mass storage devices (cameras , card readers, USB HDD, etc.).
Step 1: Disconnect all USB devices from the computer and boot the computer in SAFE MODE (Safe Mode) - press F8 when starting the computer.
If you are using a USB mouse and/or keyboard - they can be left on, but if you remove either the USB controller, or the hub, or themselves - they will not work. So it's better to boot with keyboard and mouse not USB.
Step 2: Removing Hidden Devices
1. Click START. Click Run. Type cmd and click OK.
2. Type "set DEVMGR_SHOW_DETAILS=1" (without quotes) and press Enter.
3. Print "set DEVMGR_SHOW_NONPRESENT_DEVICES=1" ( without quotes ) and press Enter .
4. Type "start devmgmt.msc" (without quotes) and press Enter r.
"Device Manager" should appear, or "Device Management" in the Russian version.
5. Click View. Click Show hidden devices.
6. By clicking "+" expand Imaging devices, Unknown devices, USB devices, Disk Drives, Storage Volumes , DVD/CD-ROM and other classes that may be related to your non-working device.
For example, USB 2.0 HDD includes classes disk drives, Storage Volumes, USB Devices
7. If you see your device (including grayed ones) in the expanded classes, right-click on it and click Uninstall in the drop-down menu.
For example, for USB 2.0 HDD, you need to remove all USB 2.0 Storage Device USB device" from the class " Disk Drives", all " USB mass Storage Device" from class "USB controllers" and gray "Generic Volume" from the "Storage Volumes" class.
Be careful not to remove the devices serving your hard drives from which Windows boots.
Step 3: Remove all oem*.inf files
1.
Click START. Click Run. Type cmd and click OK.
A command line window should appear.
2. In command line, print the following ( without quotes ) and press Enter after each command:
"cd\windows\inf"
"ren infcache.1 *.old"
"ren oem*.inf *.old"
"del C:\windows\setupapi.log"
"exit"
You can do the same using any shell "a, you just need to enable the ability to view hidden and system files(the inf directory is hidden).
NB! If you have multiple copies of Windows, you must complete this procedure FOR ALL Windows installations.
Step 4: Deleting all keys in the HKEY_LOCAL_MACHINE/Enum/USB registry branch that start with VID
Deleting VID_.... keys from the registry will cause USB devices to be recognized again when the system is restarted.
WARNING: If you have a USB mouse or keyboard, do not delete their registry branches, otherwise Windows may glitch when restarting.
You can identify these branches by clicking to "+" VID_.... key and click on the key one step down. If you see something like "Human Interface Device" or HID in the value of the DeviceDesc variable on the right, then this is just a mouse or keyboard.
1. Click START. Click Run. Type regedit and click OK.
The Registry Editor should open.
2. Navigate to HKEY_LOCAL_MACHINE\System\CurrentControlSet\Enum\USB.
3. Select and delete all (except HID) VID_.... keys.
Does not work?! Right! First the permissions on the corresponding key must be set. VID_.... register. For this:
right-click on the corresponding key to open the menu and select permissions.
choose Everyone (All) and assign Full Control (full access).
Click Apply, then OK.
4. Close everything and turn off the computer.
Step 5: Connecting the device to the computer:
While the computer is OFF, connect your device to the USB port.
We turn on the computer.
AFTER Windows is FULLY loaded and stops frantically rustling hard, connect the power to your device.
The process of detecting a new device should begin and complete reinstallation drivers for it.
PS: If after step 2 there is no execution of step 3 - I warned you.
Notes
The above procedure can also be applied to root_hub branches, but only if you do not have a USB keyboard and mouse.
The USBSTORE branch can also be deleted in step 4.
In the end, you can try to completely remove the USB subsystem and force Windows to re-recognize and install all USB drivers. In this case, you need to remove all USB devices in step 2 in the order they appear when viewed in device manager when viewing devices by connection. For example for USB Flash:
In the registry, too, respectively, completely delete the keys HKEY_LOCAL_MACHINE\System\CurrentControlSet\Enum\USB and HKEY_LOCAL_MACHINE\System\CurrentControlSet\Enum\USBSTORE .
