When Windows 10 won’t recognize your USB drive, here’s how to fix it.

When you connect a USB device to your PC, the USB device descriptor helps identify the connected device. This helps the system determine which device driver to load.

But if the USB device descriptor malfunctions, your PC won’t recognize your connected external device. Instead, you’ll get an error message that reads, ‘Unknown USB Device (Device Descriptor Request Failed)’ or ‘A Request for the USB Device Descriptor Failed.’

If you’re experiencing this issue, read on to find out how to fix this error on Windows 10.

What Causes the Unknown USB Device Error?

The ‘Unknown USB Device (Device Descriptor Request Failed)’ error can occur due to hardware or system-specific issues. Here are the various causes of this issue:

  • Your latest software update had issues and ended up corrupting the USB drivers.
  • There was a fault when you were replacing some parts of your PC.
  • You’ve made mistakes while configuring the USB driver settings.
  • The USB port is broken.
  • The USB device is damaged, corrupted, or infected with malware.
  • The USB drivers are corrupted or outdated.
  • The BIOS system needs updating.

Now, let’s explore the six ways to resolve the ‘Unknown USB device descriptor request failed’ error.

1. Quick Fixes for the ‘Unknown USB Device Descriptor Request Failed’ Error

Before you apply the detailed methods in this article, here are some quick tricks to try:

  1. Reboot your PC and see if this resolves your issue.
  2. Plug your USB device into a different USB port. If this resolves your issue, then the initial USB port is most likely broken.
  3. Plug your USB device into a different computer. This will help you determine whether the problem comes from the USB device or your PC.
  4. Disable the Windows fast startup setting. This feature boots up your PC quickly and may cause several system performance issues. So, disabling it and rebooting your device could help.

If these quick fixes don’t resolve the ‘USB device descriptor failed’ issue, move on to the next method.

2. Scan Your PC for Hardware Changes

The next method involves scanning your PC for any hardware changes. When the scan is complete, your PC should be able to recognize the connected USB device.

Here are the steps you need to follow:

  1. Plug the USB device into your PC.
  2. Open the Device Manager by pressing Win + X and selecting Device Manager.
  3. In the header menu of the Device Manager, click the Action tab and select Scan for hardware changes from the list.

Wait for the system to recognize all hardware changes and see if this resolves your issue.

3. Reinstall the USB Drivers

Faulty USB drivers could be causing this error. To resolve the issue, you’ll need to uninstall the Unknown USB Device (Device Descriptor Failure) drivers and reinstall them.

  2. Expand the Universal Serial Bus controllers section.
  3. Right-click the Unknown USB Device (Device Descriptor Request Failed) driver and select Uninstall device.

Reboot your system when the scan is complete. This should automatically reinstall the USB drivers and get rid of the error.

4. Update the Generic USB Hub Driver

If the previous method didn’t help, you can try updating the Generic USB Hub driver. There’s a chance that this USB driver is outdated and is the one causing the issue at hand.

When you finish, close the troubleshooter and restart your PC to implement these fixes. This should tackle the ‘unknown USB device descriptor failed’ error and other hardware-related issues.

6. Disable the USB Selective Suspend Setting

Disabling the USB Selective Suspend setting might also help you resolve the issue at hand.

Here are the steps for disabling this feature:

  1. Type Control Panel in the Windows search bar and select the Best match.
  2. Navigate to System and Security > Power Options > Change plan settings.
