NUT uses libusb-0.1 to access the UPS, and libusb needs something like a ugen
node (instead of /dev/usb/hid*).
A quick search yields the following:

This is not entirely unexpected. libusb does not allow specifying a USB device
by its path, hence usbhid-ups ignores "port". (There are other
parameters to specify the UPS by its USB IDs.)

The difference when you pass "-u root" is that the drivers ordinarily
drop permissions (even when started from a root shell), and the unprivileged
user doesn't even have permissions to scan the USB bus(es).
