it seems that this device has discontinuous alternate setting numbers. the bAlternateSetting jumps from 0 to 4 or 3, while usual devices have the suceeding numbers from 0. > > > ---- > #cat: /proc/asound/dev/controlC2: File descriptor in bad state that's not wrong. your device has apparently no mixer controls... together with the problem above, i fixed / improved the usb audio driver. now all interfaces on the same usb device will be merged into one card, so you'll get only one card now. it's on cvs. please give a try. btw, now descriptor proc was removed (one can use lsusb anyway). instead you'll see formats supported on each stream.
