Plugged in webcam in good working-order but can be seen. How does a computer-illiterate make himself seen?
the webcam is recognised as power going to it but it sounds like you need the correct driver installed do a google search for the make and model and go to the manufacturers website and download the driver for free once downloaded unplug the webcam run the software and then plug the webcam back in and it should recognise it properly this time.
