I installed the latest version of the PlugIn on a Odroid N2 arm64 (armv8 or aarch64).
I then selected it in TheSkyX and connect.
the EFW reports 0 filter slots and syslog is being flooded with :
Jul 26 20:02:53 obs2 kernel: [66788.464602@2] hid-generic 0003:03C3:1F01.0001: pid 10356 passed too short report
So there seems to be an issue with the HID reports (if you use lib hidapi, make sure you pass the proper report length in the report request).
In any case this renders the filter wheel unusable on arm 64 systems with TheSkyX (odroid N2+, TheSky Fusion, ...).
Can you please have a look at this as this blocks TheSky Fusions customers (in addition to other Linux arm users).
