Additional info:

USB has been working on MIPS for well over a year now.  There was a problem
early on due to non-coherent MIPS cache, but it was solved back then.

We have been using USB on global span IVR successfully.  Maybe there are
still some patches missing in linux-mips tree.  I will take a look later.
