goto /usr/local/etc/bluetooth and edit the file input.conf

Make sure UserspaceHID=true is set

you also need to have these modules loaded
uhid.ko
uinput.ko


That is all it took for me to get my MX Keys keyboard to connect to bluetooth.

thanks Paul, adding those two modules has made it work.

out of interest, how did you troubleshoot that those modules were missing?

I’ve done some work with audio controls, so I knew about uinput…….udevadm was showing no activity on connection, so I figured there was another module.  google was my friend on uhid.
