ROS INDIGO Ubuntu 14.04

So I am using visp_auto_tracker to track QR codes, I want to use this data in RVIZ. When I add a camera in RVIZ and select /usb_cam/image_raw i get the warning No Image received...

If you run rostopic echo /usb_cam/image_raw, do you see any output there?

Of if you run rosrun rqt_image_view rqt_image_view and select the desired topic, can you see images there?

are you using rosrun rviz rviz to start rviz? I've seen similar behavior in some cases when rviz is started without sourcing ros.

@Jeroenvdk , I've experienced the same issue some days ago. The problem is that I was selecting Camera in RViz. Selecting Image instead of Camera worked for me.
