Correct me if I'm wrong, but you're saying that this approach would enable
wine to work with (almost?) any USB device, which has a vendor specific,
kernel-mode driver, using the vendor's supplied driver out-of-the-box.
Sounds like the best approach to me too.

Maybe there are other people out there with the same problem as me, (or
simply a desire to get better USB support in to wine) who would be
interested in working on this too?
