i have been using an AM5N since October with no issues. Tonight, I tried to connect to the mount, and it does not, and it shows no option for a com port in the ASI ASCOM Server screen. Unlike my other devices, I get no "sound" when I plug in the mount USB port. Tried multiple USB cables, but no luck. I will contact zwo support but thought I would try here first. Camera, focuser and guide scope all connect with no issue. I am using the ASI ASCOM server as I have in the past.
