Raspberry PI Camera Module Not Detected

Make sure that:

• you have connected the camera to the right port; the Raspberry PI has two identical ports for the camera module and for the touchscreen)
• the cable/ribbon/connector is properly connected and not damaged
• you have loaded the bcm2835-v4l2 kernel module, by adding it to /etc/modules and rebooting afterwards
• you have enabled the camera using raspi-config
• you have allocated at least 128 MB of RAM to the GPU
• you are using a genuine camera module, not a "compatible" one
• the command raspistill -o cam.jpg captures an image from the camera, without complaining

The special file /dev/video0 should be present when all of the above are met.
