This patch adds the following capabilities to usbaudio.c:
- Merges support for M-Audio FastTrack USB
- Adds proper support for M-Audio Quattro USB
- Adds hot-reload support for all Audiophile, FastTrack and Quattro.
This works quite well on Quattro;
Thibault, could you please verify that it works for Audiophile?
- FastTrack "select configuration #2" quirk is present but #ifdef'd out
pending inclusion of
"usb_driver_set_configuration" function in mainline kernel. This quirk
could possibly be handled in user space anyway.
Part 2 of the patch contains documentation update.
