Well, I spoke too soon. The USB0 device will come and go with plugging/unplugging the Arduino, but only if you don't leave it plugged in too long. I can do a fresh reboot, plug in the Arduino, and if I leave it plugged in for more than about 4 or 5 minutes it will stick again, along with the call trace appearing in the system log.
This is getting really aggravating. Where can I find the source code to the ftdi_sio v1.5.0 USB FTDI Serial Converters Driver?
