linux=Armbian in this problem ;)
Problem is that X10 is not IR remote but radio. Configuration is easy in linux and works well. In linux in /etc/lirc/hardware.conf I have:
/etc/lircd.conf is standard - for Medion X10 MD8800
In Kodi remote works well as devinput without tuch any config - no problem with remote but Kodi 15 in Armbian has no HW.
So now: how to do this in Openelec - main problem how to change driver for lirc.
For me X10 is another solution to have OPI behind TV - because of CEC problem in OPI PC+
But best solution for me is have kodi-standalone (Kodi 16 or 17) working in Armbian - without desktop - maybe it is now possible...
EDIT
My foult. Can not be autoexec.sh which kills lircd and run new service with lircd.conf.
Without autoexec.sh and lircd.conf X10 works out of the box. Only modification lircmap.xml is needed - especially back button
I am using the "OpenELEC-OPi2.arm-7.0-devel-20151211000653-r21671-g0770e97" image install on a Orange Pi PC (I know this image is supposed to be for a Orange Pi 2, but I don't mind to only have 1 working USB port)
1920x1080@60 works fine on my end.
