my system configuration is indigo and ubuntu 14.04. i installed freenect and openni_camera. but when i execute the command: "roslaunch freenect_launch freenect.launch" or "roslaunch openni_launch openni.launch". it executed but show no device is connected. i already connect my Kinect to system and did all permutation -combination with connections.
....... my out look like..........................
