I suspect he means something like "audio class", "printer class",
etc. The answer is yes, sort of. What we have right now is a single
USB audio driver for OSS that attempts to implement the audio class
and also contains the inevitable long list of per-device hacks needed
to work around the fact that almost no manufacturer fully complies
with the class specification.
However, its for OSS, which is a problem, and we don't yet have a USB
framework for ALSA worked out, which is even more of a problem. Its
still unclear at this point whether the ALSA framework will be:
application<->alsa-lib<->alsa-driver<->low-level-ALSA-USB-class-driver
OR
application<->alsa-lib<->low-level-non-ALSA-USB-class-driver
the first one is easier to write, the second one is more flexible.
