Nut upsuser - Jul 2009 - Powerware 5110 UPS with nut in Ubuntu

Hi all,

I've got a Powerware 5110 UPS that I'm trying to set up with nut in
Ubuntu.  I've installed nut and configured the first two files:

$ cat /etc/nut/nut.conf
MODE=standalone
$ cat /etc/nut/ups.conf
[pw5110]
	driver = bcmxcp_usb
	port = auto
#	port = /dev/bus/usb/002/002

When I try to test this configuration with the following command:
$ sudo upsdrvctl start pw5110
Network UPS Tools - UPS driver controller 2.4.1
Network UPS Tools - BCMXCP UPS driver 0.21 (2.4.1)
USB communication subdriver 0.17
Can't set POWERWARE USB configuration
Unable to find POWERWARE UPS device on USB bus

Things to try:

  - Connect UPS device to USB bus

  - Run this driver as another user (upsdrvctl -u or 'user=...' in
ups.conf).
    See upsdrvctl(8) and ups.conf(5).

Fatal error: unusable configuration
Driver failed to start (exit status=1)


I found which device was being created by the udev rules and the device
/dev/bus/usb/002/002 does exist and the group is set to 'nut'.  (You can
see that I have tried specifying the port as this device, to no avail.)

I'm obviously missing something, does anyone have any suggestions?

Thanks,
Greg

Yes the port should be auto.
And if you use the latest libusb you should have a device
at /dev/bus/usb/002/002 that you have found.

To make a real test that it read the usb you can do the following.
Set libusb debug to 3.
sudo export LIBUSB_DEBUG=3

Then run the driver in debug (not by upsdrvctl).
sudo /path/to/bcmxcp_usb -DD -u -a pw5110

Now it should spit out some info. You end it by ctrl-c.

Report back and we can have a look.

We may have a bug here, but it is not confirmed as our tests
does not reveal it.
