[Nut-upsdev] [HCL] PowerShield Defender 1200VA supported by blazer_usb (mustek subdriver)

[Tom Clarkson]

Hi Team,

I've been experimenting with getting the PowerShield Defender 1200VA UPS working and it appears to be supported by the blazer_usb driver, although it did not have the correct permissions within udev to load the driver as the non-root user after an RPM install on Fedora Core 16.

NOTE: I had to put the MODE="777" in my udev rules or I would get "permission denied" and "failed to open device" unless I ran with the "-u root" option at the command line.

[root at localhost ~]# cat /etc/udev/rules.d/95-nut-ups.rules
