CEC remote not working

[Sytten]

I already use the apps for android, but I will try to use an old hp IR receiver because my parents aren't good with new tech and I want them to be able to use the RPi to watch movies...

The HP receiver seems to get the signal, but I will probably have to map the buttons myself. I hope it doesn't need a driver

EDIT: good news! my receiver is working, I get inputs, but I need to map the buttons. Anyway so happy!
