Santiago:

About the only commonality between your question and this list is the letters 
U-S-B.  The pvrusb2 driver doesn't have anything to do with USB audio.  In our 
case audio is carried along as part of the mpeg2 stream data from the device, 
so the ALSA subsystem in Linux is not in any way involved in this.

What you want to find out is what USB audio devices are supported well enough 
by ALSA to be useful for you.  There's no way that pvrusb2 experience is going 
to shed any light on that.  In your shoes I'd probably got look at the 
compatibility list on the ALSA project web site (google for it), and probably 
also try googling for phrases which combine the attributes / names you are 
looking for with "linux" and/or "alsa".

Sorry I can't be of much better help here, but this really isn't the right 
place to ask.
