I may be wrong but it could be using whatever user the daemons are running as but then that doesn't make sense as normally that is root unless you have changed things.
Unless you haven't logged out/in since adding your user to the dialout group? The only other thing I can think of is Debian 8 doing something odd?

I have just built a new Rivendell machine that uses such a shell command to fire a relay on a USB relay box that appears as /dev/ttyUSB0. The comand works flawlessly... if I run it manually from a command line. Rivendell, however, executes the shell script, but the script won't talk to the box unless I chmod o+w /dev/ttyUSB0 . I don't want to do that; I'd rather add the user in question to the dialout group, if I can figure out what user it is. Rivendell is running as the user 'scott'. 'scott' is already a member of the dialout group; therefore, the command must be executing as some other user, but which one? This is RD version 2.15.3 running on Debian 8. The box is a KMTronic Ltd. Model U8CR. I've used them before on Rivendell systems and have not had this problem. In the past, adding 'scott' to the dialout group always got the box working. I wonder what's changed.
