NUT version is 2.8.2_5 (I've already tried reinstalling the package)
NUT seems to think it can't find the UPS, but usbconfig shows it to be present:
[2.8.0-RELEASE][admin@janus.jhmg.pvt]/usr/local/etc/rc.d: usbconfig
...
ugen0.5: <PR1500LCDRT2U UPS Cyber Power System, Inc.> at usbus0, cfg=0 md=HOST spd=FULL (12Mbps) pwr=ON (2mA)
...
Below is the console log attempting to start NUT from the command line.
