I have an Eaton (3S 700 I think) on a Debian system. It's connected
using the usbhid driver and generally works fine.
Debian has rules to set the group access correctly, found in
/lib/udev/rules.d/52-nut-usbups.rules so its a matter of just using the
standard boilerplate type configuration and away you go.
For example /etc/nut/ups.conf is just
driver = usbhid-ups
port = auto
desc = "Main UPS"

I don't have such things, the udev rules in the nut-server package
does it for me.
ls -l /dev/bus/usb/009
crw-rw-r-- 1 root root 189, 1024 Jul 15 21:49 001
crw-rw-r-- 1 root nut 189, 1028 Aug 24 21:52 005
009:005 is the USB ID of the UPS.
This is with NUT version 2.7.2
