It looks like it is finding the ups, but can not communicate.

Try this. Start only the driver in debug mode.
/path/to/bcmxcp_usb -DD -a name -u root

Where 'name' is the tag you set in your ups.conf.

[pw5115]  <-------- this

It should spit out some info from the ups. If it does, you have a permission

The rest of your info is OK. Should work. So maybe there is some
problem with the permission on the /dev/bus/usb/00x/00x that
the ups is connected to.

From my computer. As you see it is connected to bus 002 device 003.
Yours was at 002/004, as I can see.
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 002 Device 004: ID 0a12:0001 Cambridge Silicon Radio, Ltd Bluetooth Dongle 
(HCI mode)
Bus 002 Device 003: ID 0592:0002 Powerware Corp. UPS (X-Slot)
Bus 002 Device 002: ID 03f0:0601 Hewlett-Packard ScanJet 6300c
Bus 002 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub

ls -l /dev/bus/usb/002/003
crw-rw-r-- 1 root nut 189, 130 Sep 21 19:09 /dev/bus/usb/002/003

As I run it under the nut group.
