apcupsd, USB and FreeBSD 8.1 aren't getting along

All-

It seems that something about the combination of FreeBSD 8.1 and
apcupsd connecting to an APC Back-UPS RS 1500.

Here's what I've got:
1. FreeBSD 8.1 (source compiled up to RELENG_8_1 for security fixes)
2. apcupsd 3.14.8 compiled from FreeBSD Ports
3. APC Back-UPS RS 1500

This was working fine in FreeBSD 8.0, but it appears to be broken with
FreeBSD 8.1. I've done a little debugging to try to figure out what's
going on and was best I can tell it's not able to communicate at all
with the UPS.

Here's what I've come up with so far:

This is what I think the issue is:

FreeBSD's USB stack no longer appears to generate the '/dev/usb#'
entries. I tried symlinking the appropriate 'ugen' to 'usb0',
but this
didn't help either.

Okay. Extremely lengthy email, but if anybody can help me with this
it'd be much appreicated.
