Takashi applied all these now to a new branch. Even though the changes
made to the driver should only affect devices compliant to v2 of the USB
audio standard, I could have introduced bugs when refactoring the code.

So - if anyone with a common USB audio device could try this branch and
report any regressions, that would help a lot, and make the branch merge
smoother eventually.
