After doing some research it appears to work like any other USB audio device so assuming that's the case, it should work in any audio workstation and I would suppose it either has it's own drivers and/or is class compliant. You can read that forum thread to get more details.

The USB on the PV 20 USB mixer acts as a stereo (2-channel) audio interface. It will record the main left and right tracks to a DAW. In order to record more than 2 channels to individual tracks in a DAW, you need a multitrack USB interface.
