Poseidon compatible USB Sound Card

[Moto]

Hello my fellow Amiga Brethren,

Can somebody tell me what USB sound cards are compatible with the Deneb/Subway USB controllers?  I have spent a good week searching for this answer but can't really find a definitive source of what works and what doesn't.  I have an old M-Audio Sonica and I plugged it in and it was immediately not recognized.  I see lots of $10 usb sound cards on Amazon (C-media chipset) but I don't want to buy something unless I know it works.  I'd love to be able to listen to some cleaner audio (mp3s, etc) on the Amiga.

Thanks in advance!

PS:  I have a "new" old stock 4000T arriving today!  Will post a slide show if I can get my camera working.

I'm not expecting a CBM model but I'll let you know if that's the case.

Is there a standard for all USB sound cards?  I've been through all the Poseidon docs and I didn't see any kind of compatibility list at all.

To answer my own question, it seems there is a standard.  It's called USB audio device specification 1.0 -- so I imagine that the Poseidon stack will work with any of these devices.  I wish the documentation simply stated this.

Can anyone confirm this?  I can get one of the vanilla cards for about $3.50

Yeah, there's a million of these things on amazon.  I got mine for 3.79 with free shipping.  

I saw the higher end ones on there such as Turtle Beach and Creative Labs but I figure I'd start low.  Besides even the cheapest one of these will sound much better than the poor Paula (for MP3s).  

BTW:  Amiga 4000T came in!  It's Smmmmminty new in the box but not a CBM model. I've taken pictures but I suddenly have a lot of work to do, so will post them later.  It's literally sitting next to me right now (almost as big as a person).
