I'm trying to use
```
rosrun usb_cam usb_cam_node
```
to read my web camera, but it keeps returning error: >[ERROR] [1392890872.217213339]: Webcam: expected picture but didn't get it...>[ERROR] [1392890872.252854641]: Webcam: expected picture but didn't get it...>[ERROR] [1392890872.285282152]: Webcam: expected picture but didn't get it...>[ERROR] [1392890872.317282039]: Webcam: expected picture but didn't get it...>
