Hm, I'm not sure if After is the right solution. What if your keyboard
is not attached during boot?
If your daemon is not functional if the hardware is not present, I'd
probably start it via a udev rule and SYSTEMD_WANTS.

In addition, if you want your service is stopped whenever the hardware
goes away, you can use BindTo in the service file
