Well, that did this:

g1-254(10.1-S)[5] sudo !!
sudo webcamd -d 1.3
Password:
Attached to ugen1.3[0]
Creating /dev/video0



So I looked a bit more on the VIDEO4BSD page
(<http://www.selasky.org/hans_petter/video4bsd/>), and saw that the
reader is directed:

# the following command will attach to the first detected webcam:

./webcamd

#
# The following command will try to attach to the given USB unit,
# interface and V4B unit.
#

./webcamd -d ugen4.1 -i 0 -v 0

#
# The following command will display webcam contents from /dev/video0
# by default.
#

pwcview



OK; so:

g1-254(10.1-S)[5] pwcview 
Failed to access webcam: Permission denied
***********************************************************
Make sure you have connected your webcam to the root hub
or to a USB 1.1 hub, also check your dmesg for any errors.

g1-254(10.1-S)[6] 


Hmm....


OK:

g1-254(10.1-S)[7] sudo -E !$
sudo -E pwcview
Password:
Webcam set to: 320x240 (sif) at 5 fps

And a light lit up on the top bezel of my laptop, and a window was
created that had an image of my face in it.  I was ... surprised. :-}

I think that means that it can work....

Thanks!
