Bjoern Fay d0b0fac14e [ALSA] usbaudio - Add support for Edirol UA-101 
Added support for the Edirol UA-101 (only in high-speed mode) by taking
the quirks for the UA-1000 and change them accordingly. Changes were
made in 'usbaudio.c', 'usbaudio.h', and 'usbquirks.h'
MIDI and recording seem to work perfectly (with JACK), but playback
gives some few glitches. I think that's the mentioned
synchronizing-problem in the UA-1000 quirk ('FIXME: playback must be
synchronized to capture'), so I didn't change that.
ToDo: Adding Mixer-Support for the built-in
control-panel/patch-bay/router.
