No Keyboard/Mouse support when enabling secure boot

Hi Abdulfatah Binafif，

Thanks for your post in Microsoft Community.

I understand that you are having issues with mouse and keyboard not working after enabling secure boot.



Did you disable USB in the BIOS?



You can look for the "Legacy USB Support" setting in the BIOS settings and try to enable this option.



If this option is set to disabled, some USB devices may not be recognized. This is a possible cause of your problem.

Please feel free to let me know how it goes.

No Keyboard/Mouse support when enabling secure boot

When I enable secure boot in my BIOS, I can't use my keyboard or my mouse, I have searched online to no avail, here is the things I tried already:

Tried updating BIOS

Tried unplugging them while the Computer is off then plugging them in after.

Tried going back down to Windows 10 (didn't follow through because otherwise I would lose my files)

Loading the default BIOS settings

I am running a PRIME H370-PLUS with version 3101 and also tried the other usb ports.

 

Windows 8 Secure Boot Feature: Not So Secure?

• Linux
• Linux
• Linux
• Linux
• Oh and OSX

Here is a statement from a Kernal Developer at Red Hat:

I'm not sure this exploits the legacy BIOS but rather it exploits the legacy boot method on MBR drives, injecting a signed key before the OS boots, which you are correct in that it has nothing to do with Windows 8. And the simplest fix would just be to require boot drives use GPT when Secure Boot is enabled in UEFI.
