So this looks reasonably familiar,
int0 is DFU
int1 is mixer
int2 is audio out
int3 is audio in
int4 is midi
int5 is HID
Quirk should look like the fast track ultra basically. maybe the mixer is
less broken in this device?
Should we start with just QUIRK_STANDARD_AUDIO_INTERFACE or copy the whole
data section from the Ultra quirk?
This has isosyncronous feedback for clock control needs current sound tree
usb-audio tree
