2 apcupsd problems using USB to connect on FreeBSD 7.2-RELEASE AMD64

[Chun-fan Ivan Liao]

MB: GIGABYTE GA-MA78GM-US2H
OS version: FreeBSD 7.2 RELEASE amd64
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     ((using "DEVICE ugen0" yields the same problem))
---------
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
---------

But if APC UPS is connected to the system after the system has been
started, it can be identified by the system, and running apcupsd start
or apctest is just ok.

Also, if I disable all USB-related configuraton in kernel and load
usb.ko & ugen.ko manually after the sytem has been started, the APC
UPS can be identified and running "apcupsd start" now will do just
fine. (if using /boot/loader.conf to automatically load 2 modules, the
problem still occurs)


2.
Continuing 1, if I don't use those ad-hoc, and 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
---------

Here is my system information:

# less /var/run/dmesg.boot:

# pciconf -vl > pciconf

# acpidump -dt > aura-acpidump.asl

Any help will be greatly appreciated.
