Re: freebsd 5.1 ohci driver causing a panic

dmesg part

FreeBSD 5.1-RELEASE-p10 #2: Sat Oct  4 21:04:37 PDT 2003

ohci0: <SiS 5571 USB controller> mem 0xed203000-0xed203fff irq 10 at device 3.0 on pci0

ugen0: APC Back-UPS ES 500 FW:2.e2.D USB FW:e2, rev 1.10/1.06, addr 2

Note that if the ups is plugged in when I boot up it comes in as a ugen0, but
if I plug it in after it is uhid0.  I can reproduce this issue when it is
uhid0.
