Orion Shoestring USB Guide Port Interface

The Orion 52081 is a Shoestring USB Guide Port Interface. GPUSB Check is a great diagnostic program that will let you confirm the computer-to-GPUSB-to-telescope connections are all functioning properly. For autoguiding software packages that use ASCOM to interface to the GPUSB, you can download the ASCOM platform from www.ascom-standards.org, then install the GPUSB ASCOM driver.
