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

Will to help with development, may need pointers to get started and willing to test things. I am mostly concerned with simple playback. Recording, DSP, and Midi can all come later if at all.

I'd love to be able to help ALSA support this USB sound device. I've currently got the device working in a VM on my Ubuntu 12.04 workstation. I believe I can capture USB packets. Would this be helpful to anyone? Any pointers on where to get started? _______________________________________________ Alsa-devel mailing list Alsa-devel@alsa-project.org http://mailman.alsa-project.org/mailman/listinfo/alsa-devel
