I apologize, I should have just mentioned the whole ups.conf:
driver = usbhid-ups
port = auto
The usbhid-ups driver (as with the others based on libusb) don't actually use the "port =" line, but the NUT internals still need a placeholder.
There is a whole complicated set of filters that let you match on the USB Vendor or ProductID, but if you only have one UPS plugged in at a time, you can ignore them. They default to matching anything that "looks like an UPS".

I think we take the first digit after " usb " (1) and the "device number 3", pad them with zeroes, and check here:
ls -l /dev/bus/usb/001/003
(Note that the NUT driver doesn't care about this path directly, but we still need to check permissions.)

Nope, see previous comments about "port = auto"

Actually, if things work right, the hiddev*/hidraw* devices should disappear when usbhid-ups starts, leaving only the /dev/bus/usb/*/* device.
