I've got a problem with my usb bus: it seems like the usb plugs are completely insensitive to any device I can plug in them (I've tried with a mouse and with a printer/scanner). The drivers are installed, but usb-ohci complains a lot when it starts, showing the following:

I've searched the net, and I've seen that similar messages are related to bugs in the drivers, thought by now they should all be corrected.
I've the RH 8.0 distribution, with all the updates installed.
Coould any of you point me to a solution?
Thank you very much

and the only difference I can notice between this pc and other which are perfectly functioning is that the usbdevfs only reports a single controller on the malfunctioning pc

Since my ignorance about usb is total, what I'm asking you is if the number of controllers is related to the number of plugs. If the answer is yes, I further ask where I could investigate to understand why two of the three USB plugs are undetected.
I've looked at the BIOS, but I cannot find anything related.
My usb controller is a SIS 7001 (rev 07), driven by
