Still mysterious.  Please try with this patch instead.

(Sorry for yet another delay)

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
