Can you post a "kodi log" from the LE settings addon (using build #1006) so I can see if there's anything useful in the system log? You could also try the various 5.3-rc builds - there are 8 rc builds - as that might help narrow it down (see the 5.3 PR for links). 

While trying to narrow this down, I tried older builds like #0620, #0801, #0901, #0913-#0916, and they all work fine.  The change appears to be between rc-8 and the final build.

Here is a link to the log generated from the #1007 build - http://ix.io/1XXl 

OK so just to be clear - #0909x (5.3-rc8) is good but #0917 (5.3.0) is bad?

This look a bit suspicious (from your #1007 log):

Could you post the same log, but from #0916 (ie. working PS4 controller) - or from #0909x, assuming that works - for comparison purposes? 

I had a feeling you would ask for that   Here is a log from #0916 - I had to remove a bunch of clutter from the emby plugin, but the section with pairing the controller is included - https://pastebin.com/69GNU13B

What I don't understand is why the debug messages look nothing alike...#0916 shows messages from the Joystick addon, whereas #1007 shows messages from the kernel.
