USB keyboard not responsive

[Thomas Pfundt]

Hi everyone,

I have some trouble getting my USB keyboard to work in GRUB2 made from the 
coreboot build system.

The image does appear to compile correctly, but only PS/2 input seems to be 
working. When I try to use a USB keyboard, it won't respond. I can replug it 
while GRUB is running and sometimes input will be registered, but only very 
delayed.

I included the 'usb_keyboard' module and it's also called via 'insmod 
usb_keyboard' in the included config, which appears to be loaded, but still it 
does nothing.

Is there anything else I could try or might have missed?


Kind regards!
