>How-To-Repeat:
This is 100% repeateable with mentioned BackUPS
connected to USB port using original APC cable.
1. Install apcupsd-3.10.18_1 from ports, configure it.
Here comes my /usr/local/etc/apcupsd/apcupsd.conf
UPSNAME BackUPS CS 500
UPSCABLE usb
UPSTYPE usb
LOCKFILE /var/spool/lock
ONBATTERYDELAY 6
BATTERYLEVEL 5
MINUTES 1
TIMEOUT 0
ANNOY 300
ANNOYDELAY 60
NOLOGON disable
KILLDELAY 0
NETSERVER on
NISIP 127.0.0.1
NISPORT 3551
EVENTSFILE /var/log/apcupsd.events
EVENTSFILEMAX 100
UPSCLASS standalone
UPSMODE disable
STATTIME 600
STATFILE /var/log/apcupsd.status
LOGSTATS off
DATATIME 600
2. Run usbd.
3. Run apcupsd and test that it has opened ugen using apcaccess.
4. Physically detach UPS from USB: unplug its control cable.
A couple of seconds later a panic occures.
