Segmentation fault, stopping uvc camera driver

edit

Hi All,

I have an extra logitech QuickCam Messenger VGA Webcam. When I simply try to run it with uvc_cam, it give me a error "Segmentation fault, stopping uvc camera driver. [uvc_cam_node-1] process has died [pid 7268, exit code -11]. log files: /home/btian/.ros/log/916ac8ea-21c8-11e2-9c54-002710a9471c/uvc_cam_node-1*.log"

The integrated cam of my laptop works fine with the uvc_cam. I installed guvcview, and it can switch between the two cameras without any problem. I tried the logitech webcam on another PC, same error. What should I do with the uvc_cam? Thanks!
