This is on a Compaq Professional Workstation XP1000, which is a Tsunami
system, compiled with the DP264 system setting in the kernel:

ohci_hcd: 2004 Nov 08 USB 1.1 'Open' Host Controller (OHCI) Driver (PCI)

There was a fix that went into the miata system type a while back:
http://www.uwsg.iu.edu/hypermail/linux/kernel/0110.3/0849.html

I am using kernel 2.6.12.5, though the same problem occured with
2.6.11.8.

Unfortunately I do not know enough about these systems to attempt to
copy such a fix into the dp264 system type -- I made an attempt, but it
had no effect.

If you send me a patch to try out, I can do so as the system is not
being used for anything serious at the moment. If you need more info
about the system, just ask.

Thanks,

Ilia
