You can get outside air temp through OBD (well actually CAN-bus), but you would need to write your own software to get at it though as it is not a standard parameter for normal diagnostic software. As for getting over USB, that is a totally different kettle of fish, onboard USB is normally only for the audio system and is kept well away from CAN to prevent signal corruption on the CAN-bus which can seriously mess up the car.
