Kinect problem - [/openni_camera] No devices connected

edit

Hi, there, I'm trying to connect Kinect with turtlebot, but it is not working. First of all, I was following instructions on how to "hack" kinect cable and connect it with power board which has gyro. I cut power cable as it was shown and made an adapter to connect with power board. Then, I've connected Kinect with my TrimSlice - I see green light on Kinect start blinking. I've plugged second cable into the power board and run: roslaunch turtlebot_calibration calibrate.launch After all processes has started I consistently see:

[INFO] [WallTime: 1321466338.673699] Still waiting for scan [INFO] [WallTime: 1321466338.975991] Still waiting for scan [INFO] [WallTime: 1321466339.277746] Still waiting for scan [INFO] [WallTime: 1321466339.580285] Still waiting for scan ...

Ctrl+C doesn't stop this process and I would have this output unless I will kill this process.

I was searching by error in google and here but didn't get anything which I could apply to my situation. Most of the questions about Kinect related to it work when I can't even start it. Any ideas what I was doing wrong or/and how I can fix it? Thanks. -Roman.
