I am using fuerte in ubuntu 12.04.

Whether I use roslaunch openni_launch openni.launch or rosrun openni_camera openni_node I get the following output:

[ INFO] [1349109695.908019815]: Number devices connected: 1

[ INFO] [1349109695.983442622]: depth_frame_id = '/camera_depth_optical_frame'

When I use rostopic list I can see all the topics:




But all the topics are empty, there is no information being published

Can someone please help me?

Did you try rostopic info and rostopic echo to find out if there are any nodes publishing on that topic and what is being published?

For, rostopic info /camera/rgb/image_raw, /camera_nodelet_manager, is the publisher with no subscriber, but when I use rostopic echo, there are no messages being published.

Was the kinect connected to a USB 3.0?
