title: Raspberry pi:enable camera module
body: <p>I have attached an usb camera with raspberry pi and also enable it using sudo raspi-config command . I rebooted the raspberry pi after enabling it, but it doesn't enable - so getting error (<code>error is..mmal: Camera is not detected. Please check carefully the camera module is installed correctly</code>)</p>
  
  <p>When run command (<code>raspistill -o image.jpg</code>) to capture an image, I have also run update and upgrade command to update raspberry pi but doesn't solve problem.</p>
  
  <p>And main thing when I run <code>ffnpng -i /dev/video video.avi</code>, it records video so camera working so why this error coming? And what is the solution for that.</p>
  
  <p>Is there any other way or command to cature image? plz help me. Thank u in advance.</p>
