USB keyboard crashes

Hi,

I have an ASUS A8N-E mobo, with the "USB Legacy Support" option in BIOS, but
when enabled with a USB keyboard plugged, computer fails to start sometimes
due to buggy BIOS, probably.

So I've tried disabling this option (and therefore using the keyboard as
pure USB), but there is no way to get it working under Grub2.

By the way, is a Logitech Classic 200 keyboard, and I haven't another
keyboard, neither USB nor PS/2, at the moment; when I've I'll do further
testing).

First, note that I've used the Ubuntu 10.04 version of Grub2 (1.98-6) and
the "official" Grub2 1.98 (not a snapshot, I'm not as advanced).

Second, here are the tests I've done:

With the USB Legacy Support DISABLED (thus being the keyboard purely USB)
- I've wrote in grub.cfg "insmod uhci ; insmod usb_keyboard ; terminal_input
usb_keyboard". The computer restarts every time. Then I've deleted commands
until no restarts, and I've noticed that loading uhci goes right, but
loading usb_keyboard then leads to a restart.
- I've wrote in grub.cfg "insmod ohci ; insmod usb_keyboard ; terminal_input
usb_keyboard". The computer hangs on starting.
With the USB Legacy Support ENABLED
- I've gone to GRUB console and typed lots of combinations.
- I can confirm that loading usb_keyboard without loading anything before
leads to a restart.
- Loading usb_keyboard AFTER loading uhci is the same.
- Loading usb_keyboard AFTER loading OHCI does not restart the computer, but
it stops responding. However, loading usb_keyboard throws the message "HID
found", but the keyboard doesn't work and grub do not continue executing.

I've been looking GRUB2 more than a year ago, and I found that the real
handicap nowadays is the lack of good documentation (maybe more work on the
Wiki? that's my opinion). Anyway, thanks everybody for the effort in
developing.

I hope this can be helpful. Best regards,

Jacobo Pantoja
