I think is an issue with the UDEV rules.
At the end of /etc/udev/rules.d/10-local.rules I put this line for my 
liebert USB UPS:

SUBSYSTEMS=="usb",ATTRS{idVendor}=="10af",ATTRS{idProduct}=="0004",SYMLINK+="liebert-
ups" MODE="0660", GROUP="nut", OPTIONS="last_rule"

and in 
/etc/nut/ups.conf

user = nut
[liebert]
	port = /dev/liebert-ups
	driver = liebert

Make sure also about permissions:
lrwxrwxrwx 1 root root 11  2 gen 10.34 /dev/liebert-ups -> usb/hiddev0
crw-rw---- 1 root nut 180, 96  2 gen 10.34 usb/hiddev0
