I would recommend against USB audio devices. I'm sure there are plenty of people who would swear they've had nothing but positive experience with USB devices, but just the same they are a nightmare. The USB audio specs are are defined in a manner that create a real mess for people who write the drivers for them.
>From the jack dev list:
"USB spec defines the isochronous data packets for the fixed
time length (1ms). and, obviously, 44100Hz cannot be split by 1ms in
integer."
Also, read this:

I would strongly recommend using a PCI device if at all possible.
