[Nut-upsuser] Eaton Powerware 5110 UPS

[John Anderson]

Hi,

I am wanting to use NUT to connect to an Eaton Powerware 5110 UPS using
USB to connect.

- I am using NUT 2.0.2
- I have compiled it with USB support
- I can see that the UPS is registered as connecting in /var/log/messages
    eg     usb 3-1: USB disconnect, address 3
             usb 3-2: new low speed USB device using uhci_hcd and address 4

But I don't know how to progress from here. I have used the following
commands:

mkdir /dev/usb
mkdir /dev/usb/hid
mknod /dev/usb/hid/hiddev0 c 180 96
mknod /dev/usb/hid/hiddev1 c 180 97
mknod /dev/usb/hid/hiddev2 c 180 98
mknod /dev/usb/hid/hiddev3 c 180 99

However, I'm not sure how to check that there is a link between hiddev0
and the USB device that's registering above.

- In a fit of woeful optimism I have configured ups.conf to connect to
hiddev0 but I get this error when I run upsdrvctl
            hiddev path open /dev/usb/hid/hiddev0: No such device
            Driver failed to start (exit status=1)

I have been looking to this document
(http://www.vttoth.com/ER-OF800.htm) as well as attempting to follow the
nut FAQ:

If anyone could please help me that would be much appreciated.

Kind regards,

John
