I am a little late to this discussion. I thought I would mention what I ran into when connecting an ASIAIR Pro to a new CEM40 mount in case someone is still having this issue. The mount would not initially connect to the ASIAIR Pro I had. I tried a small "unpowered" USB 2.0 hub between the cable connected to the ASIAIR USB 2.0 port and the CEM40 USB 2.0 port, and then the two communicated. The CEM40 and GEM45 have the same selection in the ASIAIR mount list. There are actually two selections, and "old" and a "New 2021". I chose the new one. JohnD

You might want to check the ZWO User Forum for the answer. A number of people with Celestron Evolution mounts were having the same connection issue. They narrowed it down to apparently a new USB to serial chip used by Celestron. ZWO needs to incorporate a new driver for it. There is a temporary fix available that references a different mount, but it apparently works. Check this thread for details. https://bbs.astronomy-imaging-camera.com/d/12787-connecting-asiair-pro-to-celestron-evolution-mount/97 JohnD

Is there a "How to use Sharpcap" .PDF or Tutorial? I cannot find one on the website or at AstronomyShed. Thanks, JohnD
