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: http://pastebin.com/pA9MLQet cheers, Greg
