Action script code does not detect secondary canon cam

Hi,

I have an action script question, Our application uses below snippet of Flex 4.5 sdk code for detecting webcams in flash players :

var camera:Camera = Camera.getCamera(); // I have logitech and canon connected , used "0" param for logitech and "1" param for canon, canon is not getting detected though logitech webcam does

                if (camera) {   

                    camera.setMode(640,480,60,true);

                    camera.setQuality(0,100);

                    videoDisplay.attachCamera(camera);                   

                }

                else {

                    Alert.show("No Camera found with your computer");

                }

Above code is fine for the Logitech webcam which am using, We have a requirement to detect Canon EOS digital cams to be recognized as well to detect with the flash player.

but its not recognizable in flash player.

Any help is appreciated!
