I have a reproducible problem with USB keyboard on at least two
machines. It is always the same story: if only one USB keyboard is
attached and no AT-style keyboard else, the BIOS legacy emulation stops
working while the hardware initialisation at boot time. BUT: If an
additional "normal" keyboard is connected, Linux does not have any
problem, I can use both keyboards, remove the old keyboard and continue
working with USB keyboard.

In the first case, when the keyboard is locked, it does help to load the
USB driver, ubskbd.o and keybdev.o, and the keyboard is useable again.

I tried hacking in Linux' init/main.c and other drivers, stopping it at
different points with wait_for_keypress. Result: even after the first
console driver initialisations, somewhere while loading the serial
driver (where the first keyboard input is accepted), the USB keyboard is
already locked, while a normal keyboard works.

I tried disabling PCI support, various drivers, nothing does help. I can
see increasing interupt count in /proc/interrupts, though nothing does
reach the console.

Gruss/Regards,
Eduard.
