Long time I didn't use my QHY-10! I took out of its box and tried it on my Debian:
* Debian GNU/Linux 11.4
* Kstars 3.6.1 Beta (compiled from sources)
* indi-qhy 2.7
* libqhy 22.7.23
Taking a preview image from the CCD tab worked for me. Also worked from the indi control panel.
Do you have any error message?
