[LAU] Newer USB audio interfaces

I noticed in the discussion on Ken Restivo's EEE-PC that he is using the MAudio FastTrack Pro. I had looked at that device, but when I looked at the Alsa soundcard matrix, it wasn't listed. Is it working out of the box? Another USB device that I thought looked good was the E-Mu 0404 USB. It is listed as not implemented yet. Is anybody using that out of the box yet? Any other ideas? I'm looking to replace my venerable Edirol UA-20 with something a little more modern since I've never been able to get its midi and audio working together. In advanced mode, midi works but no audio and vice-versa. Best regards, Bill
