Are you sure this doesn't break the hardware
initialization sequencing on some chips?

I distinctly call losing over a month of development
time on this issue, because the hardware has some
undocumented constraints in this area.  The entire
reeason the host init is so "late" is that doing
it earlier (at more logically sensible moments, (in
terms of USB specs vs Mentor silicon) broke things.
