GPUSBASCOM is a driver for Shoestring Astronomy USB Guide Port Adapter, and is designed to allow personal computers to control ST-4 compatible autoguider ports as found on many telescope mounts. After the first installation is complete, the next time you plug the GPUSB into your computer, it will remember that this device has already been installed once and will automatically recognize it. Even though the GPUSB is not an actual telescope, in terms of ASCOM, it behaves like a simple telescope mount that is capable of autoguiding.
