[Nut-upsuser] Problem connecting to eaton ups. No matching HID UPS found. Driver failed to start(exit status=1)

Thu Jul 19 23:33:00 UTC 2012

Hi

I have now placed the 52-nut-usbups.rules in /lib/udev/rules.d and called $ udevadm trigger --subsystem-match=usb --action=change, but with no luck.
I get the same error after unplug/replug of usb cable.

If I do this it will work:

root at Dalen:/dev/bus/usb/003# lsusb
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 002 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 003 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 004 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 001 Device 002: ID 18a5:0302 Verbatim, Ltd 
Bus 003 Device 002: ID 0463:ffff MGE UPS Systems UPS

chmod 0777 /dev/bus/usb/003/002

after this upsdrvctl will start. And so far upsd and upsmon is working.

So its definitely a permission problem.

Any ideas why $ udevadm trigger --subsystem-match=usb --action=change is not working?
