Hi, I had the same problem with kodi in librelec and I find this solution for the remote not is coming to be detected as joystick in the link https://github.com/denilsonsa/udev-joystick-blacklist
I only had to do this:
cd /storage/.config/udev.rules.d/
curl -o /etc/udev/rules.d/51-these-are-not-joysticks.rules \ https://raw.githubusercontent.com/denilsonsa/udev-joystick-blacklist/master/51-these-are-not-joysticks.rules
curl -o /etc/udev/rules.d/51-these-are-not-joysticks-rm.rules \ https://raw.githubusercontent.com/denilsonsa/udev-joystick-blacklist/master/51-these-are-not-joysticks-rm.rules
I know it not is valid for recalbox, but may be exist a similar option in Recalbox.
Regards.
