Post reboot the rules did not take affect nor did they appear to work when I created them and then attempted to force them with udevadm control --reload-rules && udevadm trigger before rebooting. What I had to do:
- Create the rules
- Reboot
- After reboot run
udevadm control --reload-rules && udevadm trigger
