Comment 0 for bug 1099947

I hooked my new CyberPower UPS: CP685AVR-G on my Lucid server and got this error:

  Jan 15 12:06:33 xeon upsd[5441]: Can't connect to UPS [cyberpower] (usbhid-ups-cyberpower): No such file or directory
  Jan 15 12:06:38 xeon upsmon[5445]: Poll UPS [cyberpower@127.0.0.1] failed - Driver not connected

After trying many things, I found https://bugzilla.redhat.com/show_bug.cgi?id=488368 that hint me in the right direction. The required change was to rename the udev rule like this:

  mv /lib/udev/rules.d/{5,6}2-nut-usbups.rules

Now, everything works well, without requiring "user = root" in /etc/nut/ups.conf because the udev rule now ensures the device file is owned by the group "nut":

  # find /dev/bus/usb/ -ls
