Hi Brian,
This is almost certainly a PCI issue and not USB. For a similar
sounding problem the Linux USB FAQ suggests trying noapic as a boot
option;
"Sometimes a BIOS fix will be available for your motherboard, and in other
cases a more recent kernel will have a Linux fix. You may be able to work
around this by passing the noapic boot option to your kernel, or (when
you're using an add-in PCI card) moving the USB adapter to some other PCI
slot. If you're using a current kernel and BIOS, report this problem to
the Linux-kernel mailing list, with details about your motherboard and
BIOS."
regards,
Stephen.
