No, it is due to the fact that you can run either 'usbhid-ups' *or*
'hald-addon-usbhid-ups', but not concurrently. Apparently you missed the
'packaging' part in 'docs/nut-hal.txt' that mentions:
"The HAL support in NUT must currently be packaged separatly (ie in a
specific nut-hal package) and must conflict with the classic nut
packages."
Both drivers will attempt to (re)claim the USB device but only one driver
can attach to the USB device at the same time.
