Lack of power control on hub ports is a bummer, but something I suppose I
could work around considering the specialized nature of my application.

I'll do some hacking and see if I can get things basicly working. If there's
interest in this sort of thing, I can send patches to the list and perhaps
someone with more experience in the USB stack than I have can sanitize
things for general purpose use.
