The internal hub device interfaces directly with the human-machine interface control module via a standard USB cable. A Mini type of USB connector is used to connect the human-machine interface control module and the USB receptacle. Standard USB male-to-female connections are typically used for connecting USB cables together where an in-line connection is required. An in-line cable connection is typically found between the console and the I/P harness.

When a device is connected to the USB port, the system detects the device and switches to USB as the audio source. Once connected, the device can be controlled by the radio controls.
