Why are you running it from there? Create equipment profile in Ekos and select ASI CCD as your camera and that's it. The Devices --> Device Manager is used WITHOUT Ekos.

I found the way it handled equipment very non-intuitive. It worked connecting the mount that way and so it seemed logical for the camera to work the same way. I was starting just by using Kstars to control the mount and was then using Firecapture for imaging but wanted to hook up the camera to kstars as well so that I could evaluate moving off Firecapture (more likely for DSO work).

I'll head off to RTFM and see if that helps
