Try booting the kernel with "irqpoll". Example:

Check if that helps.

Well, I just don't know.
What kernel architecture do you use? ppc or powerpc?
In case you use the former (which is deprecated),
you might want to try the latter.

(-: Please follow my advices:
1. DO NOT remove the mailing list from CC: (and the chance anybody is
able to help you!)
2. post the output of lspci -vv.
Next step is: contact the guys in the linux-usb mailing list.
Regards,
Clemens
