Greetings,

I am fairly new to USB dev (in linux in particular, but also in general), but I
would very much like to try to get support for the above device working in
snd-usb-audio.

- Is this an appropriate place to discuss snd-usb-audio?
- Are there any recommended reading pointers for the quirk table?
   - or any highly recommended USB reading material that I might not have found?

I patched parse_audio_format_rates_v2(), get_sample_rate_v2(), and
set_sample_rate_v2(), and through some sort of beginner luck was able to get
aplay audio out of the first two channels. That was incomplete hackery though
(eg fixed sample rate), and I would like to learn how to properly add quirk
support. There have been other reports that this device worked OOTB, but I
fail to see how!

I've also been examining the traffic to the device with wireshark and a
win7 vm, but the learning curve for USB is a bit steep, so I am digesting. (:

If anyone can provide suggestions on lsusb output alone, here's what I have:

cheers,
Greg
