Cannot get IR receiver to work properly

  • I have a pretty old but great streacom chassis with the built-in USB IR receiver. Not the FLIRC SE one, but the regular, first one. If I remember correctly, it was recognized as a Holtek device back in the OpenElec days. It's running LibreElec 10.0.1 on an older Asus E-350 ITX motherboard.

    It used to work great with a generic Lenovo branded MCE remote; I guess an RC-6 one. This remote recently broke, so I've bought a One for All programmable remote.

    I can't get this remote to work properly though: it seems for every button the first keypress is registered, but the second one isn't. Therefore it's nearly impossible to navigate the menus using the 'arrow' keys on the remote.

    Now, I want to check whether the remote actually sends the second keypress, but if I follow the LibreElec guide, I can't even get the ````ir-keytable to recognize the IR receiver as it says No devices found.

    Any advice on how to operate from here?
