Weird. Maybe try a different USB cable? Or test with another computer?
Which is consistent with what I see in Tools > Serial Port. Granted, in the Mac System Preferences > Bluetooth, I've turned Bluetooth off altogether, so I'm not sure why even these two appear. So is it possible that the PDA-Sync is interfering, and if so, how do I turn that process / connection off?
