[Freeswitch-users] GSMopen USB dongle permission denied

[Dušan Dragić]

I agree with Iskren, there is probably no need to add a udev rule in this
case. Adding the user to the dialout group is simpler.
Just one thing, with usermod you can use the "-a" (--append) option to
achieve the same result as with gpasswd:
usermod -a -G dialout freeswitch

Of course udev is can still be used if you want to create permanent
symlinks for usb modems or something like that.
