Comment 42 for bug 1099947

sorry for slow response, but I'm little overloaded last few days

all these without user=root in config file

1)please add output of
id nut
id uucp
lsusb
find /dev/bus/usb/ -ls

2)in /etc/udev/rules.d/52_nut-usbups.rules try changing MODE
ATTR{idVendor}=="0463", ATTR{idProduct}=="ffff", MODE="664", GROUP="uucp"
to
ATTR{idVendor}=="0463", ATTR{idProduct}=="ffff", MODE="666", GROUP="uucp"

if it changes anything (make sure there is nothing nut related running before testing: ps aux | grep nut | grep -v grep )

Change it back to 664.

3)try to change selinux mode to permissive (if you have it in enforcing mode: sestatus)
setenforce 0
try if it changes anything (make sure nut is stopped completely) and change it back to enforcing
setenforce 1
