Yes.  You must specify the USB unit and address, which you
can lookup with usbconfig.  For example, when the camera
attaches as ugen1.2, you must specify "1.2".

Personally I have written a small wrapper script that is
run via /etc/devd.conf.  So, when I attach the camera,
devd calls my wrapper script.  The script calls usbconfig,
parses the output and starts webcamd with the correct
unit and address arguments.  (webcamd terminates auto-
matically when I detach the camera, so I don't need a
separate call for that.)

webcamd comes with a pre-configured entry for devd.conf
(it uses $cdev), but that one never worked for me on
FreeBSD 8.  Don't know why.  (The wrapper script was
trivial to write, so I never cared much.)
