The Xonar U1 enables its digital output with a vendor-specific command;
see snd_usb_mixer_apply_create_quirk() in sound/usb/mixer.c.  It's
possible that the U3 uses the same command; try adding your product ID
there.

Sweet!
That absolutely worked like a champ!
Tested it, and not 
only do I get the telltale red light coming out, but I quickly hooked it
 up, and tested it to my stereo over optical, and it worked perfectly!

Is there somewhere I should forward this to?
The devel list?

Thanks again for the hint!
