I launch the driver pointgrey_camera_driver using launch file and it works normally when I subscribe to the topic, for example, /camera/image_raw. I do rostopic hz /camera/image_raw and it get all the frames 30fps but when I stop that I re-execute it again I get no new messages from rostopic hz and rostopic list shows that all the topics are still publishing.

I've every time to stop the driver and re-launch it again.. Do you know how to solve that? I tried to subscribe through a node (simple subscriber on c++) and it is the same issue.
