Hello,
I have a USB IR receiver that previously worked with Intel NUC + LibreELEC 8.x. I have now moved it to another system (AOpen Digital Engine DE6100) with LibreELEC 9.2. Everything works except remote. This is troubleshoot done so far:

No devices found
I'm not expirienced in linux so I would ask for directions on what to do next.
Thanks,
