Maximus X no longer recognizing USB keyboard at bios screen
Hi, I recently updated the bios to allow me to use an Intel i9-9900k cpu and ever since, I cannot use my USB keyboard to enter the bios. The USB keyboard works fine once I pass the bios screen and enter Windows 10. I can use a wired keyboard for the bios and made sure to enable "Use legacy USB devices" but that didn't help. Does anyone have any suggestions? It really isn't a big deal, I just want to figure it out.

Hi
Try switching EHCI Hand-off To Enabled, sometimes the Legacy USB also need ENABLED rather than AUTO
If you are plugged into a USB 3 port you may also need to diable the xHCI
Hope this helps
