I don't know how your BIOS works, but it could easily be that it's disabling "USB" not just "onboard USB" ... try not disabling "USB". Then configure your system to just not use "uhci" or "usb-uhci". If that doesn't work, then I suggest you ask over on the linux-kernel list ... your problem is a

I've seen the recent messages about OHCI and PCI on embedded (?) systems and thought this would be a good time to ask: I have a dual P3 system with a Tyan motherboard. The on-board UHCI basically doesn't work (It isn't wired properly to the APIC, and even in "noapic" mode it doesn't work, the U
