Reading files from Panda II SD card via USB

Is it possible to hook up the FEZ Panda II to the PC and have the PC recognice it as a thumb drive and enable the user to browse, open and copy files?

From the Key Features it states;
[italic]Specialized libraries to configure USB port to emulate devices like thumb-drive, virtual COM (CDC), mouse, keyboard[/italic].

So how is this done? Can anyone point me in the right direction…
