IR receiver driver is not loaded

  • 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:

    LibreELEC2:~ # ir-keytable

    /sys/class/rc/: No such file or directory

    No devices found


    I'm not expirienced in linux so I would ask for directions on what to do next.


    Thanks,

  • The logs look fine,


    The Ortek IR receiver shows up as keyboard+mouse input devices and isn't handled by the rc-core subsystem so it won't show up in ir-keytable and you can only use it with the remote it was bundled with.


    I did a quick test here on RPi4 with the remote+receiver and it worked out of the box.


    so long,

  • The original remote is broken, I was thinking of using a second one with this IR reciever. So, I must get another IR reciever ?

    Yes. I'd recommend getting an (HP branded) MCE USB receiver, which is very well supported in Linux (and LibreELEC).


    so long,
