Webcam stopped working on Thinkpad Edge 15

New Thinkpad Edge 15



Messages from tray that a USB device is not recognized.

Device manager shows no integrated video device

I have uninstalled the Unknown USB and installed the .3M camera driver repeatedly.


Used automatic installed tools and tried online tools.


Nothing seems to work. Please help.
