I wonder if the way to solve this is by adding a rule<br>

there another way ?<br>

I have tried to change the permissions in /dev but they always revert to 660<br>
after a time.<br></blockquote><div><br>The devices in /dev/ are recreated with each boot. This explains why they loose the permissions. udevd is responsible for creating them at boot time, following some rules. You need to modify those rules. If I remember correctly, they are located in /etc/udev/rules.d/.<br>
