I just received my new Alienware X51 R2 recently. I start to test on my new computer. Then I find out the front two USB ports do not work! My USB device is functional cause it works when I connect it on the back USB ports. I am not sure what problem is it? I tried to update and install the driver too on Dell.com. It is a new pc and it is so inconvenience if the front USB ports do not work. please help
