Ok, with little confidence it would work, since I could find no very good
info on USB & FreeBSD, and there was no response to my query on the subject,
I decided in a "what the hell" moment to get a USB drive and see what
happened.
I have a LaCie 80G drive. It was $250 for 80, USB 2, and if it works it
should be pretty darn cool.
It is recognized by the kernel, so I thought I was doing pretty well, but
when I try to actually do anything with it, I run into trouble. Here are
some messages from /var/log messages, first hte successful boot stuff and
then the failure messages:

The set of error messages above were returned when I did a simple
dd if=/dev/da0
PS: I might not recieve mail for a couple days so don't be surprised if
responses are a little slow. Based on previous response to USB queries on
the questions list I doubt that excessive responses will be a big problem.
I'm including the questions list here more as an "FYI" sort of thing.
PPS: Why, oh why is there a /dev/ad0 and a /dev/da0? What do they stand for?
It's darn confusing and it makes me nervous as heck doing "dangerous"
operations where I am one swapped letter pair away from wiping out my primary
drive!
