Since I migrated to Mountain Lion, the USB serial ports to which the Arduino is connected are no longer visible to the Arduino app, menu (Tools -> Serial Port). It just shows the interfaces via Bluetooth.

The serial ports that appear on my Mac:

Mac Arduino serial ports menu

I've tried installing the VCP drivers and reinstalled the Arduino. I tried to run an older version of Arduino IDE and have even reinstalled the Mac OS X from scratch.

None of that solved the problem... I really need to communicate with my Arduino, how I can fix this?
