Still mysterious. Please try with this patch instead.

I'm not sure the debugging patch here was properly applied/installed, but I think so. In any event, perhaps with this patch, and definitely for your previous 2 patches, updated for the 3.19-rc7 sources, I get the following errors when I try to load snd-usb-aduio:

So the call that must be failing is:
err = snd_card_register(chip->card);
and of course this all works with the quirks table modified for the ur44. I'm at a loss. Any further debugging suggestions would be greatly appreciated.
thanks,
Cyrus
