Nut upsuser - Dec 2013 - Installing NUT for PowerWalker VI 1500 LCD

Since the provided drivers come with absolutely no installation
instructions, I turned to NUT.

The compatibility list says "blazer_usb" should be used for
PowerWalker's
devices, so that's what I put in my conf:

[pwvi]
        driver = blazer_usb
        port = auto
        desc = "PowerWalker VI 1500 LCD"

Since I use Ubuntu Server 13.10 so I installed nut from apt.

The product information PDF for the device in quesetion is
http://www.powerwalker.com/datasheet/Line-Interactive/PowerWalker%20VI%201500%20LCD.pdf

Below is the output from several commands:
I tried to look through the maillist archives but found nothing useful.

$ sudo upsdrvctl

Network UPS Tools - UPS driver controller 2.6.4
Network UPS Tools - Megatec/Q1 protocol USB driver 0.08 (2.6.4)
No supported devices found. Please check your device availability with
'lsusb'
and make sure you have an up-to-date version of NUT. If this does not help,
try running the driver with at least 'subdriver', 'vendorid' and
'productid'
options specified. Please refer to the man page for details about these
options
(man 8 blazer).

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?

Yea, I disconnected the cable to check and there are also no other USB
devices on that computer. I also tried to plug it in some other port,
just in case that would help.

He said he had permission problems, so he basically just removed the MODE part.

I tried it out now and starts OK:

Since the permission change helped, I can now continue with the
configuration. Thanks for the help :)
