Thanks for *your* help on *my* problem!!!

Yes, it's been the right lsusb dump. The reported device name is a bit 
strange indeed. In /proc/asound it is listed as F8R which is is a bit 
more reasonable.

I've tested your patch. Unfortunately I don't get any sound. 
snd_usb_audio_next_packet_size() returns from the 
"subs->stream->implicit_feedback" branch. But the return value is always 
0. ('frames' is returned, not the  0 from the if (WARN_ONCE...) statement).

Any ideas how to proceed?

Thank you very much again,

Felix
