The latest SeaBIOS git has preliminary support for USB keyboards.
I've tested this on qemu and on my epia-cn.
For info on obtaining SeaBIOS see:
http://www.coreboot.org/SeaBIOS
This support is still a little "rough" - help with testing would be
appreciated, but don't expect it to be fully functional.
Known issues:
- only uhci controllers are supported - no ohci (nor ehci)
- not all keys are mapped (eg, no numeric keypad)
- no keyboard auto-repeat
- no keyboard led support
- if one types fast, they may see dup keys or missing keys
- no hub support (keyboard must be directly attached)
- usb bandwidth is not optimized (no scheduling)
That said, I can control the SeaBIOS boot and navigate through a grub
console with my usb keyboard.
