Freenect_launch depth camera does not send messages

[TomBrunner]

Hi,

I'm quite new to ROS and CPP but what im trying to do is use face detector (http://wiki.ros.org/face_detector) with the kinect camera.
The problem I am having is that /camera/depth_registered/image_raw does not send anything until I echo it.
When using rostopic info it does say it is subscribed to by the face detector (and published by /camera/camera_nodelet_manager).
So what I would like to have is that I do not need to echo it first.
Can anyone help me with this?

with kind regards,
Tom

p.s. I do not have the same problem with the RGB camera
p.p.s I am using to change the topic face_detector is listening to to the one from the camera_nodelet_manager. Without this the system does not work.
