Have a look at the 'inputplug' program:

     https://github.com/andrewshadura/inputplug

It can run a script automatically when the keyboard is re-connected. Here is
how I use it in my ~/.xinitrc:

     …
     # Ensure polish accents are re-enabled when keyboard is re-plugged
     inputplug --command ~/.local/bin/xmodmap-polish.sh
     …

Best,
