Hi Eric,

   Thanks for the suggestion.  I applied Josh's patch, and that seems
to have fixed the problem within dynamic_reconfigure.  I think
camera1394 might be working now -- I'm getting some intermittent
results because I think my camera may be occasionally exceeding the
power limits of the USB host bus on the beagleboard.  I am going to
try connecting the camera to a powered hub and see if I can get more
reliable results.  Thanks to you both again for your help.
