Hi 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.

> $ 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

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.
