i think you the laptop might have been damaged. This usually happens when a higher power rated device is placed in you usb.
usually a usb 3.0 can give till 900mA , So please keep it in mind while using devices.

Most likely your Webcam has been affected ( ive seen webcams being affected first when you mess with the usb ports)

Try returning it

hope it helps mate
