I have installed Cheese Webcam Booth from ubuntu software center but my when I run this software I am getting following message/error.
"No device found"
I also installed Camorama Webcam viewer but it also does not work and I get the following error
"Could not connect to video device(dev/video0) Please check connection. "
My laptop is Dell Inspiron 3521 which is certified for ubuntu here
But still Webcam is not working. I am using Ubuntu 12.04.2 LTS 64-bit.
Do I need some drivers for Webcam? How can I fix this?
