This is most likely either an endianess problem in the UHCI controller
code, or an interrupt problem. The UHCI code in recent 2.4 kernels
(2.4.6 and onwards, I think) supports big-endian hosts. The UHCI code in
the mainstream 2.4.2 did not support big-endian hosts, and I don't think
the HardHat kernel was any different.
