Save the code as a mmm, "activate_keyboard.c", next do
   gcc activate_keyboard.c -o activate_keyboard
give the binary permissions of execution with
   chmod +x activate_keyboard
and copy activate keyboard to a location, where only root can see it, like /sbin
   sudo cp activate_keyboard /sbin/
Finally, make or edit a boot script to run this program at startup.
