Ok, great.

> It should run as user "nut" in Debian. You may want to reinstall the nut-server package, and check the post-inst error messages to make sure that the "nut" user is created, and that it is in the "nut" group as well.

The user nut and the group nut have been created..

> Not sure that is where the "user" declaration is being parsed. upsdrvctl just passes arguments to the drivers via the command line (including "-u", although that is not read from the configuration file, but from upsdrvctl's command line).

https://github.com/networkupstools/nut/blob/master/drivers/upsdrvctl.c#L60

I'm quite sure that it is the place where the config file is parsed...

And the init script of the debian package don't explicitly append "-u nut" in wheezy. See the attached patch in my first message.

> Can you show us the exact configuration syntax you are using?

8<-----/etc/nut/ups.conf------
user = nut

[liebert]
    driver = usbhid-ups
    port = /dev/usb/hiddev0
    productid = 0008
8<----------------

> There are some fixes that were added in 2.6.4 to try and work around incorrect exponents in the voltages. You can try starting the usbhid-ups driver directly, adding "-DDD" to see if any messages are logged about "assuming correction factor =". It could be that we did not cover all the different ways those values could be wrong.

Ok, i will give it a try.

Regards.

Paul.
