udev dynamic MAC address

Hi,

I am trying to write an udev rule to handle my phone in tethering mode.
Unfortunately the MAC address is dynamically changing every time the phone is connected.
I tried multiple options (https://wiki.archlinux.org/index.php/Ne … evice_name) + different proposition in other forum but I am not able to make it work, it is like it doesn't not detect my device.

I have tried to use  ATTRS{idVendor}=="04e8" or/and ATTRS{idProduct}=="6863" or trying also some DEVPATH instead of but no one seems to work..

Any idea?
Many thanks
