How to configure UPS with USB connection

Question

I was unable to setup nut on a server for the UPS Eaton 5E with USB connection. All results what did I get was that driver is not running and UPS is not recognized. What kind of driver is suitable for me and what kind of settings? Unit is Eaton 5E.

result of $ lsusb -v

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).

Driver failed to start (exit status=1)

Update: I tried to connect a desktop linux Xubuntu 12.04, which detected the UPS and UPS vendor via usbhid-ups driver, but did not detected any battery state and shows battery as discharged (what is not true, server is running on it several minutes with no troubles) and fiel technology as Unknown.

Solution 1

Try to use the config from this blogger: http://risc-a-day.blogspot.hu/2014/09/getting-my-ups-to-work-with-linux.html

(Excerpts:

lsusb
...
Bus 008 Device 002: ID 0463:ffff MGE UPS Systems UPS

... edit /etc/nut/ups.conf and add section for the UPS device itself:

...

[myups]
    driver = usbhid-ups
    port = auto
    vendorid = 0463
    pollfreq = 30

...

$ sudo upsdrvctl start

...

$ upsc myups

Solution 2

once try these things,

You can use lsusb to find out the bus and device number

Then change permission to the device

        chmod 0666 /dev/bus/usb/[bus number]/[device number]

as for details go with rouble starting Network UPS Tools with a Eaton 3S UPS

mode is 'standalone'. I did try option 'netserver' as well without any result. I tried usbhid-ups driver with no result as is described in my initial text.

By the way, there is an Eaton 5E, not 3S

Although your answer is 100% correct, it might also become 100% useless if that link is moved, changed, merged into another one or the main site just disappears... :-( Therefore, please edit your answer, and copy the relevant steps from the link into your answer, thereby guaranteeing your answer for 100% of the lifetime of this site! ;-) You can always leave the link in at the bottom of your answer as a source for your material...

looks promising, finally on 5E, will try it asap.

This complements Grin's solution. It is necessary to put the device file as 666 after configuring nut. Perfect, dude. Saved my life ;)! Thanks.
