    Is COM 3 correct? Can you have the Arduino IDE get the board status on that com port?

    TOOLS -> Get Board Info

    Because if the com port is correct then I would suspect the Arduino has a bad USB port.

    HOWEVER... look here (it is an Arduino error after all):

    I have had this issue a few times myself and it is either a BAD COM port used (i.e. you needed COM4 not COM3) or a bad driver (reinstall the Arduino drivers) or a bad Ardiuno. That last one is not common :) Those boards are pretty sturdy.
