Reactivate the USB bus controller

Solved/Closed
Nathanat -  
Hello everyone,

It seems that I stupidly disabled the USB Bus Controller, which means that I'm on Windows and I can no longer use my mouse or keyboard to reactivate it.
I even tried to reinstall Windows but it still didn't work.
Could you find a solution to this problem?

Thanks in advance, Nathanat

    Hello,
    If you have reinstalled Windows (reinstall or reset?), it would be necessary to install the 3.0 driver if you only have USB 3.0 ports. To use your keyboard and mouse in the BIOS, you need to disable the xhci.

      After that, you need to reinstall the 3.0 driver and reactivate the xhci (I don't know if the USBs work automatically without a driver. As long as the xhci is disabled, the ports are 2.0, but depending on what you do, it's not that bothersome).

      Hello, I have the same problem as Nathanat, what is xhci?

      xhci is USB 3.0; if it is enabled, the 3.0 ports will operate as 3.0, and if it is disabled, the 3.0 ports will function as 2.0.

      If xhci is enabled and the 3.0 driver is not installed (normally integrated into Windows 10), the USB ports will not work; disabling xhci allows them to switch to 2.0 and make them functional (limited speed to 2.0 as a result).
