I checked out my ZWOptical ASI120MM which I want to use as a guiding cam. The cam was detected correctly in INDI Control Panel but connecting to it failed. The reason was that the download package was lacking an udev rules file. I searched the web and found one, copied it to /etc/udev/rules.d and was able to connect to the cam.
Please check your download package.
