I just installed the latest Stellermate on a RaspPi4.
It found and connected to my iOptron mount, ZWO guide camera and Moonlight focuser,
But it fails to even see my Canon 6D. It keeps asking me to check if it's powered on, which it is.
I cycled the power, rebooted the Pi, changed USB cables, changed USB ports, etc. I then tried the same cable on my Mac and the Canon camera connected fine.
Why won't Stellermate see my camera? It's set to bulb, the power is full, and the memory card has loads of space.
Do I need to install anything else on the Pi like some canon EOS driver?

Solved! The camera's own internal WIFI was turned on, and this camera cam't do both at the same time!
Once I turned off WIFI on the camera, the USB connected.
