[ros-users] openni_camera not publishing any data

[Tom Birch]

Hmm, there does seem to be something wrong with XnSensorServer. If I plug
the kinect usb in, and then run the node (roslaunch openni_camera
openni_node.launch) then I see XnSensorServer is running. Neither stream
(/camera/depth/image or /camera/rgb/image_color) have any data according to
image_view. When I ^C the openni launch, I see XnSensorServer is still
running, and if I kill it it doesn't die, but rather hangs around until I
unplug and then re-plug the kinect.

Why do you say that about the usb ports? I can verify that I can get both
streams in the freenect-glview app, I don't think it's an issue at the USB
layer...

cheers,
Tom
