4 apcupsd problems using USB to connect on FreeBSD 7.2-RELEASE

[Chun-fan Ivan Liao]

OS version: FreeBSD 7.2 RELEASE
apcupsd version: 3.14.5
UPS model: APC-MGE Back-UPS RS 1000VA (BR1000TW)
UPS cable type: usb

3 important lines in /usr/local/etc/apcupsd/apcupsd.conf:
---------
UPSCABLE usb
UPSTYPE usb
DEVICE
---------
Other lines are default.


Problem Description:
1.
The APC box cannot be detected when connected to the FreeBSD system on
system boot. (apcupsd_enable="YES" is set in /etc/rc.conf )

The associated messages in /var/log/messages:
---------
May 10 16:08:27 aura-cosmetics apcupsd[901]: apcupsd FATAL ERROR in
bsd-usb.c at line 735 Cannot find UPS device -- For a link to detailed
USB trouble shooting information, please see
<http://www.apcupsd.com/support.html>.
May 10 16:08:27 aura-cosmetics apcupsd[901]: apcupsd error shutdown completed
---------

2.
Continuing 1, if I unplug the connecting USB then re-plug it to the
same port, the USB cannot be identified.

The associated message in /var/log/messages:
---------
May 10 16:36:17 aura-cosmetics kernel: uhub0: device problem
(TIMEOUT), disabling port 3
---------

3.
Contiuning 2, changing the port to plug the USB will do, and
/var/log/messages reads:
---------
May 10 16:41:07 aura-cosmetics root: Unknown USB device: vendor 0x051d
product 0x0002 bus uhub1
May 10 16:41:08 aura-cosmetics kernel: ugen0: <American Power
Conversion Back-UPS RS 1000 FW:7.g9a.D USB FW:g9a, class 0/0, rev
1.10/1.06, addr 2> on uhub1
---------

But when starting the apcupsd now using [apcupsd start], there is no
"freebsd startup succeeded" message appearing in /var/log/messages.

However using [ps ax| grep apcupsd], there is the following associated
procedure in the standard output:
---------
1264  ??  Ss     0:00.01 apcupsd start
---------

4.
The last problem continuing 3, if stopping the apcupsd now using
[apcupsd stop], the following error messages occur in
/var/log/messages:
---------
May 10 16:48:11 aura-cosmetics apcupsd[1270]: Valid lock file for
pid=1264, but not ours pid=1270
May 10 16:48:11 aura-cosmetics apcupsd[1271]: apcupsd FATAL ERROR in

---------

Any help will be greatly appreciated.
