[Fix] Unknown USB Device (Device Descriptor Request Failed) For Windows 7, 8 & 10

When running Windows 10 and tried everything like uninstalling, updating, etc. Also, updated the drivers using Driver Easy but still getting the error.

Unknown USB Device (Device Descriptor Request Failed)

Solution 1: Delete it from Registry

  • Open the Windows PowerShell (Admin) and type: chkdsk /f/r/x.

It will inform:

The type of file system is NTFS. Cannot lock current drive. Chkdsk cannot run because the volume is in use by another process. Would you like to schedule this volume to be checked the next time the system restarts? (Y/N)' select Y then re-boot your machine and follow the on-screen prompts.

  • After the reboot, again, Windows PowerShell (Admin) and type: sfc /scannow and allow the process to finish.

Now clean the registry with a reputable program such as CCleaner then take a note of the device/s name and select ‘run’ from the Windows menu list bottom left.

  • Type regedit without the apostrophes and open the registry.
  • Select Edit then Search… and type the brand name of the device in the search bar.

The search results will point you to a series of strings of the device that was giving the (device descriptor request failed) code 43 error message.

Every string in the registry with the name of your device will need to be deleted but ensure it is the device’s name from which was generating this error example; Logitech, Seagate, whatever brands device name that has produced this error code. Ensure you have removed every last trace of your device’s name in the registry.

  1. Then after completion use the CCleaner again to remove all known traces and re-install the device’s software if this is the case.

Your device will come back to life without the error message and start to work again.

Reasons, why this happens, are not entirely certain but often PCs pick up spyware/malware/viruses and corrupt the registry’s strings other times, updates and upgrades in particular overlap information and again, corrupt the software and its registration process.
