USB-to-Serial cable not detected
As described previously, you must install the drives before connecting the cable. If GPS TrackMaker ® is not able
to detect the new virtual serial port, certainly the cable drivers were not installed correctly.
To solve this problem, just reinstall the drivers and plug the cable into another USB port. Microsoft Windows will
detect it automatically.
