Webcam Diagnostics (CamDiag) is a simple assistant which gathers many system and webcam-related information in a single place. It makes it easy to identify some driver installation problems or USB issues: red circles will signal serious issues and yellow triangles will signal minor issues. Right-click a reported issue to access the context menu and click the Fix menu (if available) so that the program attempts to fix the issue or shows you a possible way to fix it.
