I also am wondering if the message about libusb driver missing might be
the real problem.
Checking my system, I see this:
===================
[root@mythtv dev]# ll /dev/bus/usb/001
total 0
crw-rw-r--+ 1 root root 189, 0 Nov 9 08:21 001
crw-rw-r--+ 1 root root 189, 1 Nov 9 08:21 002
crw-rw-r--+ 1 root root 189, 2 Nov 9 08:21 003
crw-rw-r--+ 1 root dialout 189, 3 Nov 10 09:43 004
==================
That looks to me like the udev rule worked.

Check /dev/hidraw6, as noted in your dmesg output (and any other *hid*

a udev rule changes the perms on the dev for nut . . .
I admit I am not fully tracking the latest NUT developments, but I don't
think the current drivers use /dev/hidraw*, especially when the drivers
mention libusb. (Once the libusb-based drivers start, they should detach
the kernel's HID drivers such that the corresponding /dev/hidraw* device
disappears.)
You are correct that the udev rules need to change permissions on one of
the UPS /dev nodes, though.
From Bill's lsusb output:
[root@mythtv ups]# lsusb
...
Bus 001 Device 004: ID 0764:0501 Cyber Power System, Inc. CP1500 AVR UPS
The libusb path for this UPS would typically be /dev/bus/usb/001/004
