I recently got a new mount. The Ioptron CEM 70 C. This is the USB2 version with a USB connection to the mount. I have a. RPI4 with 4 G memory with Astroberry loaded. The Astroberry was loaded around Jan of this year 2021. My previous mount was an EQ6 running EQMod. This mount connected instantly and first time to Ekos so I am surprised I am having all this trouble. My configuration is the Astroberry serves as an Indi server which connects to Kstars running on my PC. I choose the Iopron V 3 driver in the kstars Ekos configuration and CEM 70 in the Indi server. My RPI and PC are connected via ethernet on a local network. All my equipment cameras, focuser filter wheel connect to Ekos on the PC so I know am am doing something right. In the Ekos connection panel under telescope mount it lists my port as ttyUSB0. Thatdoes not work. When I scan the mount connection it recommends trying ttyACM0 but that does not work. Thats on the PC side so I am surprised The Windows interface is worried about what is happening on the RPI Raspbian side. I don’twant to just keep trying random changes Idon’t really inderstand.  Thanks Lou Zyla
