H87 Pro4 Keyboard and Mouse not working in BIOS

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   I'm having the same problem with my Fatal1ty Z370 Professional Gaming i7.

It used to work. Now I don't have mouse or keyboard until Windows 10. I can use the restart to UEFI tool, but same thing. No mouse or keyboard in the BIOS.

I haven't been brave enough to clear the CMOS. I'm scared to death that the mouse and keyboard won't work still, and then I won't be able to set the CMOS to even be able to boot any longer.

Were you able to solve this, @futurejump, or anyone else have an answer?

Based on another, more recent post, I did try removing the videocard, and using the onboard video, but behavior was exactly the same.

	Hi, i suddenly have the problem that all my usb devices only start working at the windows 10 login screen. Therefore i can't access the bios. With the "restart to UEFI" tool i am able to access the bios but i cant change anything because keyboard and mouse are not working. I tried multiple keyboards, i used them before in the bios so i know they should work. I didn't change any setting. If i Clear CMOS with the Jumper the keyboard and mouse are working fine. But once i boot into windows and then reboot the pc the problem appears again. So i have to clear the CMOS every time i want to change something in the bios. Can you help me?
