APC UPS control system - Manual (Page 30)

FreeBSD-4.11
NetBSD-2.0
NetBSD-1.6.2
OpenBSD-3.6
FreeBSD-5.3 has had the most testing since it is the primary platform on
which the driver is developed. The other platforms and versions have had
somewhat less testing. The only architecture tested so far (on any platform)
is i386, althought there is no reason to think it will not work on other archs.
If you run the driver on a new platform version or architecture, please report
your experience to the apcupsd-users mailing list.
KERNEL CONFIGURATION
You will need to rebuild your kernel in order to disable the uhid driver.
uhid is not sufficient for apcupsd at this time and we need to prevent it
from grabbing the UPS device. You should disable the following devices in
your kernel config file (comment them out):
FreeBSD (you WILL NOT lose use of USB keyboard and mouse): uhid
NetBSD (you WILL lose use of USB keyboard and mouse): uhidev, ums,
wsmouse, ukbd, wskbd, uhid
OpenBSD (you WILL lose use of USB keyboard and mouse): uhidev, ums,
wsmouse, ukbd, wskbd, uhid

CHECKING UPS IS RECOGNIZED BY THE KERNEL
After building a properly configured kernel, reboot into that kernel and
plug in your UPS USB cable. You should see a dmesg log message like the
following:
ugen0: American Power Conversion Back-UPS RS 1500 FW:8.g6 .D USB
FW:g6, rev 1.10/1.06, addr 2
