Hi Alex, (or anyone else trying to use Ubuntu on an Orange Pi5 for astrophotography)
Have you encountered any issues connecting your devices to Ekos while using Ubuntu on an Orange Pi5 for astrophotography? I am facing an issue where Ekos is unable to connect to my QHY183c, I get a pop-up asking if the device is connected and powered on. Yes, it is. In addition, the serial connections are displaying a port failure error of "No such file or directory." I am curious to know if you have faced similar issues.

A few months ago, I came across the Orange Pi 5 and thought of using it as a replacement for my RPi4 to take advantage of its stronger machine and faster speeds of the NVMe connection and SSD. With the help of a friend we designed a housing allowing us to combined a few other devices under the OPi5's roof, such as a 7-port powered USB hub, focuser PCB, EL panel PCB for flats and automated shutter control, and a 12v power supply for three barrel jacks. After some hard work, the device powers up, headless with a VNC desktop via X11. Unfortunately, I couldn't get tightvnc working, as there was an issue running kstars, and it kept showing an error with Qt.

I have plugged the USB hub into the OPi5's USB A 3.0 port. The focuser and the EL panel are plugged directly into the other USB A ports, while the mount, camera, and guide cam are all connected through the hub. However, only the ZWO guide cam seems to be connecting. I have used this same setup with RPi4 without any issues.

I ran "ls /dev/tty*" and get like 63 root available serial connections but no indication of what is connected. I also ran "lsusb" and this is what I got:

Any suggestions would be very much appreciated.
