Subj : USB Controller failure:

Just yesterday, I got my old computer (AMD-K6-2, 500 mHz, 184 megs
RAM, etc) to dual-boot Windows 98 with Red Hat Linux 8. They both seem
to work fine, but a problem... the USB Controller (SiS 7001) isn't
working at all in Linux, and will only work in Windows if i switch
drivers (Between SiS 7001 and Generic) while working in Windows (and
it'll stop working if i re-boot with Windows). This is all the more
pressing since the computer uses a USB HID mouse (Microsoft 2.5 button
infrared, an intellimouse?). Thus i spent 10 minutes pounding my
keyboard in frustration until i figured out how to open the 'Red Hat'
menu to open a terminal or to log off.

Whenever I boot Linux, when the "USB Controller...." check is
performed, i get a bunch of gobbledygook, followed by "insmod usb-ohci
failed" and a big red [FAILED] - when all others get green [OK]'s.
After the check the mouse's infrared light turns off, and remains off
in Linux. If i boot Windows, the light stays on, even as Windows
cannot recognize the mouse. When i open up System - properties tab,
the USB controller is lit up as malfunctioning. When i switch from SiS
7001 or Generic to the other, the mouse works and continues to work
for the rest of the session with Windows. It stops working next boot,
however.

If it helps any, I'm multibooting with GRUB. And, newbie that i am (at
least to Linux), I got the 2 CDs from Linux for Dummies, as the "Red
Hat Linux 8 Publisher's Edition."

When I first booted Linux after install (bypassing GRUB), the mouse
worked fine. When I booted Windows... not so fine. And when I booted
Linux again... same thing.

As far as I can see, the problem factors into one of the following:

1. Whatever Linux check's doing is screwing with the USB card.
2. Windows and/or Linux reconfigured something to screw both up.
3. GRUB is doing something (but what?).
4. Bill Gates is somehow responsible, with an evil conspiracy with SiS
to prevent Microsoft mice from working on computers with Linux. Maybe
not.

Am I in the ballpark? The USB-controller and the mouse both worked
fine with just Windows on the computer.
