I’m still working on this, investigating and testing but in the mean time I also wanted to reach out and see if anyone else is having or had similar problem. SGP says its connected to the nStep focuser but isn’t controlling it. Does nothing. I can however control the focuser using the GCUSB-nStep ascom program which I have to launch manully and connect the focuser. SGP is showing green connected but not controlling the focuser is happening when the focuser is connected to a USB hub (Dlink in this case). If I plug the focuser directly to the laptop, and connect SGP to the focuser, SGP then can control the focuser but it also automatically launches and connects the focuser in the GCUSB-nStep program at the same time. Seems to be hub issue but I’m uncertain. I’ve checked ports and only the focuser is using com4. The hub is powered as well. I’m going to keep trying to figure it out but if anyone has a suggestion I’d appreciate the input.
