Thanks Lenny. I am not on a pc. It does work and connect when I am on a pc - but that is not running Stellarmate/Kstars/Ekos. When I am on the Raspberry pi based Atikbase/ Stellarmate with Kstars and Ekos it doesn’t connect. It reliably connects and operates every time when I plug it into my PC. It has yet to connect with Stellarmate on the Raspberry pi. Powered USB hub or not. Brand new cable, or the old one. Won’t connect. It probably is not identifying the port. Stellarmate/Kstars/Ekos is not auto-recognizing the port for the AVX. It is looking more like a software error or configuration error.
