I am using usb_cam driver to use a camera. When i try to run the driver using rosrun usb_cam usb_cam_node , I get the following error. Screenshot from 2016-06-30 17:43:53.png

Cannot identify '/dev/video0' : 2, No such file or directory

Can i know how to fix this ?

Well, does the file /dev/video0 actually exist? What is the output of ls -al /dev/video0?
