XBee Explorer USB Windows cannot ID device.

I am having trouble with one of the SparkFun XBee Explorer USB boards. I bought 2 and the one works just fine and the XBee modules all work. When I plug in the working one it is assigned a com port with no trouble at all. When I plug in the other board I get a system pop up that says:

USB Device Not Recognized

One of the USB devices attached to this computer has malfunctioned and Windows does not recognize it. Click…

The other identical XBee explorer works fine and I can use to communicate and use it as advertized. I have tried other computers and rebooted my PC to see if it is something else with the exact same message. When I plug in the USB cable the power light is ON and the Rx and Tx LEDs flash together a few times. I think I have a bad board. It never worked and I tested it right out of the package.

Any suggestions or should I try and get a warranty replacement?
