ML150 G3 USB question

[akauffmann]

I've tried with both RHEL 4 and 5 with the same results. I've disabled USB in BIOS and booting with no extra parameters.

00:1d.7 USB Controller: Intel Corporation 631xESB/632xESB/3100 Chipset EHCI USB2 Controller (rev 09)

Booting with nousb parameter sure enough makes them disappear, but the keyboard stops working.

First question:
What USB is the BIOS option supposed to disable. It sure isn't disabling these 5 ports.

Second question:
Are the PS2 ports bridged to the USB bus?

[Mauro Rusignuolo]

it's not clear the first question.
about the second, the answer it's: no.

bye.
