[Nut-upsuser] something messed up ttyUSB*

[Tim Dawson]

Either adjust the udev rules to create the tty devices with the desired owner/perm, or add the nut user to the appropriate group to have access to the device . . .Worst case, you can "brute force" by putting your chmod in rc.local so it resets at boot (but that is pretty gross as solutions go . . .)
