I have finally got round to getting my FunCube Pro working under OS X Lion and Linux (Ubuntu 12.04). The main issue turned out to be the firmware was too old for the latest Qthid application. I managed to run an older Qthid application (2.2) under Ubuntu which allowed me to upgrade the firmware. After that my FunCube Pro worked fine with Qthid 3.2 on OS X Lion and Ubuntu.
After setting it up I installed DSP Radio 184.108.40.206 on OS X Lion I successfully received stations on 2 meters (144MHz).
