openni_launch problem

asked 2012-07-25 21:13:12 -0500

I tried to use the openni_kinect. There is no errors or warnings when I installed openni_kinect as the instructions in http://www.ros.org/wiki/openni_kinect, but when I tried to use openni_launch by typing

roslaunch openni_launch openni.launch

in the terminal,

It has many errors as follows:

Found 23 error(s).

I need some more info from you... Are you on a turtlebot? Are you using a kinect camera? Is it powered from the turtlebot?

Assuming you have the turtlebot with a kinect: I had some trouble when I plugged the kinect into the USB 2.0 ports. Try it int he USB 3.0. If that doesn't fix it, run this and post the output:

I was under the impression that the Kinect did not work with USB 3.0 at all... Did you possibly mean it the other way around?

Nope. I've always used it through USB 3.0

Interesting, I don't have USB 3.0 to test it on, but I have seen quite a few posts such as this and this that say otherwise.

Although this post has a comment that says with newer kernels it might be possible. Regardless, I suppose it is a moot point until the @LiliMeng responds.
