Kinect not detected

edit

Hi, I previously posted an issue regarding errors in openni drivers installation (http://answers.ros.org/question/2297/openni-drivers-installation-errors). With the answer to this question i was able to install the drivers successfully. Then i ran the openni_camera node's openni_node.launch file, which says the devices is not connected.

aravindhan@rrc-laptop:~$ roslaunch openni_camera openni_node.launch
