Solution of the error : No matching device found.... waiting for devices

There may be permission issue with KInect. That's why it's showing like no devices found. In gazebo , the camera node publishes image topic. But in real hardware it is done by Openni.launch (Kinect launch ) file. So we need to give permission to the given port. Give the following commands - $ lsusb

Your device will be listed $ sudo chmod 777 -R /dev/bus/usb

You have given permission to the port

$ roslaunch openni_launch openni.launch
