dpptam/map not being published

[rnunziata]

dpptam/map is not being published when i use my webcam via usb_cam. The only difference is in the header from what I can see...since running the bag file works in the example. Here are the differences. There are no error messages. Node graph looks ok. Any idea on what is going on....the marker and other topics are ok...just the point clouds are not published.

I published using cv_camera with allows me to specify the mode...now the message heard are identical but I still do not get a pointclould when using the usb cam....but it works with the bag file......?

I am beginning to think there is something not right about the webcam...its a logitech. though it works with other ros pkgs such as ptam....
