Ick, you don't really want to try to support all of the USB changes in
the same driver, now do you? Why not just live with two different
drivers.
The ALSA people eventually gave up trying to do this... :)

You end up with crud like this because of trying to support old kernels.
Why do you care about kernels prior to 2.5.69? If so, your USB kernel
checks are wrong, as 2.5.0 didn't have those API changes :)
