UPS on FreeBSD

[login at istop.com]

Good afternoon,

I have attached a UPS to FreeBSD host using USB cable provided by APC.

Environment:

This is Back-UPS RS 1500 and connected to FreeBSD server via usb port.

Here is /var/log/message and apcupsd get started at boot time without any
problem.

Oct  7 16:19:42 bsd20 apcupsd[497]: apcupsd 3.10.6 (28 October 2003) freebsd 
startup succeeded

The STATUS is missing in the above status report. Other thing that by un-
plugging the UPS from the power outlet, the system does not shutdown 
gracefully neither display/wall any warning about the UPS. The output from 
the  /usr/local/etc/rc.d/apcupsd.sh status is same as above. Basically, 
system crashes since UPS is not getting any command to follow by 
the /usr/local/etc/apcupsd/apccontrol program.

By changing the DEVICE to /dev/uhid0 in the apcupsd.conf file, 
when starting the apcupsd, I get:

# /usr/local/etc/rc.d/apcupsd.sh start
 apcupsd
# apcupsd FATAL ERROR in dumbsetup.c at line 91
Cannot open UPS port /dev/uhid0: Device busy
#

Any thoughts and/or workaround to have UPS working on FreeBSD especially via 
USB cable? Thanks!
