It's been a month, and off and on I've been looking at this more. It
appear xkb allows per-device settings, but I've run into several

First, I can obtain the current settings using xkbcomp $DISPLAY
file.xkb, I then edit it to replace the letter 'c' with the letter

To test, when I use file.xkb (xkbcomp file.xkb $DISPLAY) this works as
expected. Of course, I then reset it to the original behaviour because
I don't really want to not be able to type the letter c at all.

However, when I try to specify only a specific device (in my case the
bluetooth mouse on id 14), this does not seem to change anything. My
keyboard works the same (c does not change to q) and the mouse also
outputs c rather than q. However after trying to 'type' c on the
mouse, my keyboard then outputs q instead of c. This is despite the
fact that the keyboard should be id 11.

This behaviour sometimes seems to happen the other way as well, a
change (c becomes q) in the id 11 keyboard may suddenly affect the
mouse, not immediately, but after typing some characters for testing.

Does anyone have any idea what could be going on? Could this all just
be a limitation of trying to use xkb with a bluetooth mouse?
