First, can you be more specific about where this error message came from? My guess is: you ran the Zune install program under **** and plugged in the Zune when prompted, and got a dialog box with the message. Is this correct? I recommend just plugging the Zune into the machine without running any “helper programs” and see what happens. If nothing happens, maybe try posting the output of “lsusb” (run it in a terminal, of course) and I’ll see if I can be of more assistance.
