Hey,
On my debian Dual 550MHz Pentium III machine, I am unable to get usb working. I didn't notice anything obvious in the bios that would disable USB. Any suggestions would be greatly appreciated.
I have tried several kernels, most recently 2.6.10 and 2.6.11.5. I have also tried booting with variations of
append="noapic acpi=off pci=biosirq"
Upon loading uhci_hcd module I see the following
$ dmesg
