The original Ubuntu NUT package has the necessary udev scripts to  
change ownership of the UPS's USB device to the "nut" system user, but  
these scripts are limited to the USB Product IDs that we know about  
when that version of NUT is released.

You can add the following line to scripts/udev/nut-usbups.rules.in,  
then run 'make nut-usbups.rules' in scripts/udev:

SYSFS{idVendor}=="09ae", SYSFS{idProduct}=="1008", MODE="664",  

I believe the "nut-usbups.rules" file (not the .in file) gets  
installed in /etc/udev/rules.d as "52-nut-usbups.rules".

There is also a 'refresh' command for udev, but it may be simpler just  
to unplug and replug the UPS after installing the .rules file.
