USB APC ups does not show up after boot

[Andrei Kolu]

FreeBSD 7.1-PRERELEASE #0: Wed Oct 22 23:55:13 EEST 2008
Motherboard: Gigabyte X48-DS4

After boot-up I see messages /var/log/messages:
-----------------------------------------------------------
Oct 24 09:27:13 testiserver apcupsd[734]: 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>.
Oct 24 09:27:13 testiserver apcupsd[734]: apcupsd error shutdown completed
-----------------------------------------------------------

When I reinsert UPS data cable then ups shows up:
-----------------------------------------------------------
ugen0: <APC Back-UPS ES 550 FW:828.D2 .I USB FW:D2, class 0/0, rev 
1.10/1.06, addr 2> on uhub1
-----------------------------------------------------------

Restart apcupsd and everything is working just fine. Is it motherboard 
problem with USB or something is broken in FreeBSD?
