As i do not have a normal USB keyboard at the moment (last december i
borrowed one) i have tested latest git again with my wireless Logitech
keyboard/mouse combo.
See attached log.

If you prefer a log with a normal USB keyboard i will try to borrow it
again.

I have tried to debug this a little but had no succes yet.

I tried to understand the OHCI spec.
Am i right that you use the "LEGACY SUPPORT INTERFACE SPECIFICATION" via
emulation interrupts and Legacy Support Registers 100h, 104h,(i/o
address 60h) 108h(i/o address 60h) and 10Ch(i/o address 64h) ?

I have "# CONFIG_PS2PORT is not set" because my target doesn't have a
ps2 keyboard controller.

I could not find the Legacy Support Register: HceControl (100h) being
setup in SeaBIOS .(for emulating 60h + 64h)

I think i found some code for that in Geode VSA that i suspect to be
wrong, but i'm not sure yet.

I also attached a lspci with coreboot/SeaBIOS + linux for reference.
