Thanks Bob,
I'm ccing this to the developer of capture in case he has some ideas
about this.
When I reboot without the rc.local dodge if I go to start my camera I
can't initialize it unless I turn the camera off and back on again once
the machine has booted. I'm using a program called capture based on
libptp http://www.ucl.cas.cz/~petr/plant-growth/ .

normally I just issue a:
$ capture start 
command to initialize the camera. If I turn the camera on boot the
machine and issue this it doesn't work. I get an error message saying
"can't initialize the camera" If I boot the machine then turn the camera
on it works fine. I am trying to build a system that allows someone to
turn on the camera, boot the machine and walk away. I haven't been able
to find any error messages in the system logs. Any more thoughts on
this? Thanks!
Jim
