Hi,

When I start 3dsensor.launch I get:

[ INFO] [1414430559.252574176]: No devices connected.... waiting for devices to be connected

When I rosrun openni_camera openni_node by itself I get the same error.

I've trawled rosanswers looking for a solution, but nothing's worked yet. : C lsusb lists the kinect; I've followed the suggestions here, and the suggestions here, and the suggestions here, and the suggestions here, and here to no avail.

This is being run on a turtlebot2, and both the turtlebot and the workstation are on 14.04 trusty and indigo igloo. The kinect is plugged into the usb 2.0 port.

lsusb yields:

Bus 002 Device 004: ID 0bda:5605 Realtek Semiconductor Corp. 
Bus 002 Device 009: ID 045e:02ae Microsoft Corp. Xbox NUI Camera

Turtlebot specs are: Ubuntu 14.04 Trusty Memory 1.8 G Processor Intel Celeron @ 1.50Ghz Graphics intel ivybridge mobile OS type 64 bit

I'm at a loss. does anyone have suggestions?

I'm not entirely certain if it's related, but when I start up my minimal launch I get this:

  • I've updated the question with the contents of lsusb.

  • The kinect is listed there, as it should. I started the kinect by making sure everything is connected. All the lights are green.

  • Which computer do you want the specs for, the workstation or the turtlebot?

turtlebot's spec would be helpful

It turned out the solution was to get an openni patch. This resolved the connection error.

However, I now have a minor issue with RVIZ.

From the 3d Launch I get:

[ WARN] [1414934636.270421799]: Camera calibration file /home/turtlebot/.ros/camera_info/depth_0000000000000000.yaml not found. 
[ WARN] [1414934636.270594235]: Using default parameters for IR camera calibration.

rostopic echo camera/depth_registered/image_raw produces numbers, and I get a point-cloud visualization.

i've the same problem but im getting the openni drivers from apt-get install ros-indigo-openni-camera and ..-launch and executing roslaunch openni_launch openni.launch. What do you mean with "getting an openni patch"? Are you installing those drivers from git before indigo's openni packages?

@lokus, That's where you should be getting them. As far as I know, openni actually doesn't support the Kinect. The patch which I linked to fixes this. I didn't have to remove and re-install anything, I just downloaded it alongside my existing stack.

Experienced a very similar (or the same) issue. I've worked it around by roslaunch freenect_launch freenect.launch. This may not work on different environment (see a Turtlebot issue for more info) though.

dpkg -p ros-indigo-openni-launch ros-indigo-freenect-launch | grep Vers
