[Nut-upsuser] trying to use powerware 3110 USB with NUT

Ok.

We have to look at the 'device'. The problem is that
this type of drivers don't use any ordinary /dev entry.

As i understand you have the /etc/hotplug/usb/libhidups
script in the right place and chmod +x.

And your /etc/hotplug/libhid/usermap is setup with
your vendor and product id.

One thing, if you use the script from 2.1.0 it reads:

if [ "$ACTION" = "add" -a "$TYPE" = "usb" ]; then
  chown root:nobody "$DEVICE"
  chmod 0660 "$DEVICE"
fi

So it sets the device to be owned by root and group nobody.
Change the line
  chown root:nobody "$DEVICE"
to
  chown root:nut "$DEVICE"

If you run it as user nut.

I use Wolfgangs script.

--------------------------------
echo usbups: device = $DEVICE >>/tmp/usb.log

NUTOWNER=nut

if [ "${ACTION}" = "add" ] && [ -f "${DEVICE}" ]
then
    chmod 0000 "${DEVICE}"
    chown "$NUTOWNER" "${DEVICE}"
    chmod 0644 "${DEVICE}"
fi
--------------------------------------------

This has the advantage that i can check the
/tmp/ups.log for the device.

cat /tmp/usb.log
usbups: device = /proc/bus/usb/002/002
usbups: device = /proc/bus/usb/002/002
usbups: device = /proc/bus/usb/001/002
usbups: device = /proc/bus/usb/001/002
usbups: device = /proc/bus/usb/001/002

Then i can check the 'device'

ls -al /proc/bus/usb/001/002
-rw-r--r--  1 nut usb 52  6 okt 00.01 /proc/bus/usb/001/002

That it has the right owner and that it exists after plugging in the ups.
