The problem with the webcam turned out to be that the required driver is
not in the mainline Linux tree---the webcam worked under native only
because ubuntu ships the extra driver.
So the patch attached to the parent is good AFAIK. It could do with
being tested with a wider range of USB devices than I possess. Owing to
the way it hooks into the Linux USB stack, there are likely to be a few
more commands that need to be emulated in the BE to get specific devices
working. The Linux USB folks were talking about allowing drivers to
bind to devices rather than interfaces which would make things cleaner.
