GM_GPSStartTrackingUSB |

| Currently only Garmin USB devices are supported. |
Starts tracking a GPS device connected to a USB port. The GPS will actually be tracked on a background thread, so this function will return quickly and possibly before a connection is established.
If a callback function is provided, it will be called on the GPS thread whenever new GPS locations are received and when the GPS tracking state changes.
