I didn't dig UVC much yet but probably if UVC is used for more things
than webcams I should fork usb_webcam to make an uvc-specific driver
and leave the other one for old-style webcams.
Depending how UVC works with respect to existing non-protocols (more
like over-usb register read/writes and that's it), it might be cleaner
to split.
