You could also try to use indi-ssag. The Starshoot Autoguider is in fact a QHY5.

However this driver works a bit different. For indi-qhy, the firmware for the QHY5 is loaded by the udev kernel mechanism, with the help of fxload and a udev rule which can either be found in /lib/udev/rules.d or /etc/udev/rules.d. In my case it is 85-qhy.rules.

The indi-ssag driver needs to find an uninitialized SSAG or QHY5, because it loads the firmware on its own. For this the loading of the firmware via udev must be prevented. If 85-qhy.rules is found in /lib/udev/rules.d the cleanest way to disable is "ln -s /dev/null /etc/udev/rules.d/85-qhy.rules", because a rule file under /etc/udev/rules.d shadows a rule file with the same name under /lib/udev/rules.d.

What do you want to use the QHY5 for? It's quite outdated and especially the Linux firmware has some (hidden) issues (Indeed for some strange reason, Windows loads a different, slightly simpler and I assume slightly older firmware ).
I probably should write down my findings about the QHY5/SSAG from my experience in building a QHY5 clone and analyzing the firmware, but I didn't find the time yet.
