The configuration file looks good.

What is the exact NUT package version (including the Ubuntu-specific version number)?

^ This is most likely your UPS. 

Josu Lazkano just emailed this list last month with a similar problem (NUT 2.6.4 on Debian):

http://thread.gmane.org/gmane.comp.monitoring.nut.user/8180

There should be an entry in /lib/udev/rules.d/52-nut-usbups.rules for 0665:5161, but apparently the one in the Debian 2.6.4 package wasn't working:

ATTR{idVendor}=="0665", ATTR{idProduct}=="5161", MODE="664", GROUP="nut"

Josu said that creating this udev rule solves the issue:

SUBSYSTEM=="usb", ATTRS{idVendor}=="0665", ATTRS{idProduct}=="5161", GROUP="nut"

But given the additional "goto" statements in the NUT udev file, those should be equivalent.

What version of udev and the Linux kernel do you have on your system?
