USB in 2.4

[Francois-Rene Rideau]

Ahem. I cleaned up the source code after committing Matan's patch,
because it didn't compile as is.
The 2.4 patch makes the screen flicker at times.
Maybe bad ArbiterBias or something?

I'll do more testing when I have time...

Experience is the worst teacher.  It always gives the test first and
the instruction afterward.
