hoping for somebody's guidance here. 
I have an MXQ Pro 4k android tv box S905 Amlogic doing a dual boot via SD card Libreelec 8, with Kodi 17.2 rc. Works fine including the factory remote. I also have a 2.4G Air mouse (worked ok under Kodi 17.1 pre Libreelec) that loses all controls when booting to Libreelec. Only the power button works.
I tried following the steps here to make this remote work again. I tried the instructions above by making a 'rule' file (51-these-are-not-joysticks-rm.rules) and dumped it inside udev.rules.d folder but still the remote won't work.
is there something i missed along the way?
thanks in advance!
