This became relevant when working with Arduino and the Arduino IDE, where the relevant user must be added to the uucp user group.
uucp
/etc/group defines the groups of the system.
/etc/group
Display group membership with
groups user
If no user is provided, the current user's group names are displayed.
Add users to a group with
gpasswd -a user group
If the user added to a group is already logged in, the user must then log in/out for the change to take effect.
