I want the wpf app to detect the usb or cd drive when I inserted

I created a wpf app with a list box having some images. Now I want me to insert a usb or cd into the system, having some images that my application should start automatically when I inserted a usb or cd with images, and the application should ask whether to add these usb or cd images to the default application.

Any PLZ source code ... any suggestions also ...

Thanks in advance
