I wrote my own, since I haven't been able to find anything (other
than the linux driver) that supports the CPiA.  Mine is a Creative
Webcam II.

Basically when I tell it to grab an image, I always get the correct
amount of data from the isochronous endpoint.  However, about 75% of
the time, the header is corrupted.  When it works, the image comes
out fine though.

I believe I did find a small bug in the ugen isochronous reading
that could result in some corruption once in awhile, but fixing
that didn't seem to help... (I'll send a pr in a few days about this.)

This is 1.5_BETA with a -current ugen.c on i386, by the way.
