Hi Jack.
Here is my report on using camera1394 with cturtle installed from
.debs and using the camera1394 version that comes with cturtle
I'm using two Point Grey FL2G cameras.
Here's a console dump:
rosrun camera1394 camera1394_node
[ INFO] [1276679648.477523418]: dynamic reconfigure level 0xffffffff
[ INFO] [1276679648.516876117]: Found camera with GUID b09d01008190a5
[ INFO] [1276679648.517085850]: No guid specified, using first camera
found, GUID: b09d01008190a5
[FATAL] [1276679648.523132429]: [camera] exception opening device:
[Camera1394::open]: Unable to get iso data; is the camera plugged in?
coriander displays both images just fine.
In fact I quickly tried cameradc1394 driver from CMU's repository and
that was successful in publishing images (verified by image_view)
But this is not optimal as having one driver that is always kept
up-to-date is a better option.
Trying to install camera1394 from svn trunk rosmake complains

I realized this may not be related to camera1394.
