Try using a USB device with a different USB port

In some cases, the device request descriptor may not work because the USB port is not working properly. In this case, you need to check each of the available USB ports separately. This way you can determine if the problem is caused by the port or not.

Connect the USB device to one port at a time. Repeat the process until you have tried all the USB ports. This will make it easy to determine which port is causing the problem.

Connect the USB device to another PC

Your computer may also be causing a USB descriptor error. Possible causes could be a bad sector of the Windows operating system, outdated drivers on your computer, or non-functioning USB ports. Trying a different computer may help to resolve the situation.

Unplug the USB device from the computer and plug it into another computer. If it is recognized, you will know that the problem is with the computer you were using before, not with the USB flash drive.

Uninstall the USB driver in the device manager

In this case, the computer needs to be reinstalled, possibly due to corrupted or outdated files. Follow these steps to remove the USB flash drive from the Device Manager.

  1. Open the Device Manager. Then open the Run dialog box by pressing the Windows and R keys at the same time. Type “devmgmt.msc” in “Run” and then click “OK”. The device manager will open.
  2. Next, expand the “Universal Serial Bus Controller” category. You may find an unrecognized USB drive in the options. The error “USB device unknown” must be marked with a yellow sign.
  3. Right-click on the USB drive and select the “Delete” option. Then restart your computer after successfully uninstalling the drivers.
