Unknown USB Device (Device Descriptor Request Failed)

Question

Hello, I have a recurring issue regarding an unknown USB device on my laptop computer (Lenovo Legion 5i). When this issue occurs, it disables my keyboard and prevents me from using any of the keyboard buttons, forcing the use of an external keyboard. All other functions of the computer work as intended, just the on-computer keyboard.

The first time this issue occurred, my attempts of fixing the computer caused a BSOD fatal error loop, which I then sent to the local Best Buy Geek Squad for repairs. I have received the laptop in working condition on 5/6/2022, and when the same issue occurred, I followed all known methods to try and resolve the problem (restart computer, uninstall keyboard driver -> restart, disable -> enable driver, system restore, full reset) with no success. I ran a device troubleshooter and found an unknown USB device with an error. I manually updated the driver for said USB device, which cleared it up and had no issues until today.

As of today 5/18/2022, the on-computer keyboard has become unresponsive again and the same device issue has returned, and the previous methods I have mentioned do not work. All latest updates have been downloaded. What could be the issue and is there a solution?

Hi KevinChung22,

Thanks for your update. In this case, try to contact the laptop manufacturer to perform an update of the BIOS, and if the problem persists, it will be necessary to have a depot repair or hardware replacement.

I hope this helps, and feel free to reach back if you need further assistance.

Best regards
