I got one of these yesterday and only had a quick chance to plug it in this morning before heading to work.
From lsusb it appears with the same ID as the solo, and as such the solo software installs. I did have to revert the alsa version as indicated elsewhere in the forum.
http://forum.linuxmce.org/index.php?topic=10428.msg72593#msg72593Seems there are a few variations of this model available from phoenix audio, the one I received was MT202-PTT.
If I get a chance to play with it later I'll update.
