Just to let you know I am trying to use a kinect sensor with openni and slam but am running into a few problems. I keep running into this error "No devices connected.... waiting for devices to be connected" inside my terminal. I've tried using freenect_launch, I've tried installing KinectSensor-unstable repair files, and I've tried different methods like using openni2 and nothing is different. Here's what my terminal shows when I put in "roslaunch openni_launch openni.launch" into the terminal after pressing enter.
Can I please have help? The kinect LED is green so I know it is a software error. Thank you.

Just to let you know if I type “roslaunch freenect_launch freenect.launch” I get strange warning and eventually an error. The error says "Stopping device RGB and Depth stream flush"Here is what it says in the terminal below.

stream flush means nothing is subcribed to the kinect topics if you open rviz and conect pointcloud2 to the kinect topic(depth registered points set depth_registration to true with rqt) then the warning will go away
How do you subscribe to the Kinect topics? You said that if I open rviz and connect to pointcloud to the Kinect it will go away. I don’t know how to do that. Thank you though.
Just to let you know I got rviz to run. I added a pointcloud2 and I did expand it but one problem. There are two topics under pointcloud2 and I don’t know how to set the frame to one from teh camera ei camera link. I noticed there are a few errors in the GlobalStatus tab I am not sure if that is important. It says “Fixed Frame [map] does not exist”. What should I do? Thank you.
I am new to robot programming and I am having similar problem with Kinect connection usin openni or freenect. I am using robotino.
When I connect the kinect to my laptop, it works fine. But when I connect the kinect with Robotino and do the “roslaunch freenect_launch freenect.launch” … I get the message:
[ INFO] [1465902396.516936708]: No devices connected… waiting for devices to be connected
