A couple of devices confirmed
I've been successful using both the M-Audio Fast Track Pro, and the USB out on the ART Voice Channel tube mic pre-amp. In both cases, I'm just recording at 16bit/44.1kHz, so I'm not sure about support for the higher bit/sample rates, but my results have been really impressive. I have a song post in the "My Music" forum that used these two devices and my Indamixx laptop.
