First, a question for people who own Minix NEO U9-H + a USB RF remote. Do you have any problems with the RF remote? Are all the RF keys read under LibreELEC?
I don't know if it's for all Amlogic devices or only NEO U9-H. I have tried it on several and with these images:
CoreELEC 8.90.1
LibreELEC-S912.arm-8.2.4-Subtitles-ff
LibreELEC-S912.arm-8.2.4.1
All the same problem.
The problem is that not all the RF buttons on the remote are read (HOME, VOLUME for example). Under the official LibreELEC and Intel NUC, those buttons work.
These remotes are regonized as 2 devices, one Keyboard and the other Keyboard/Mouse. These LibreELEC community builds read the first Keyboard strokes but
cannot read the second keyboard. More details here.
So for summary, this is specific to the community builds. The official LibreELEC does not have this problem.

It is also not specific to this remote. I have a MINIX NEO A3 remote and the same problem.
