You said your Intel board has also problems with the handoff.
Could you try the follwing patch, because the EHCI documentation
says that the OS must set the EHCI_USBLEGSUP_OS bit and then
wait until EHCI_USBLEGSUP_BIOS is cleared. The kernel never
uses the EHCI_USBLEGSUP_OS flag at the moment.

What hardware has problems when we do the handoff? Your system and
mine experience a delay, but it doesn't

It wasn't just MIPS. IBM has a very popular blade system that has huge
issues with this, and I think there are some other IBM systems based on
the same BIOS that also do bad things if we don't grab the USB
controller away from the
