Things You'll Need
Instructions
Connect the flash drive to the USB end of the Xbox-to-USB cable.
Connect the Xbox end of the USB cable to one of the controller ports.
Turn the Xbox on and begin playing a game. Because the XBox simply uses a different form of USB cable in order to connect to Xbox controllers (and the memory cards that may be connected to the controllers), the XBox will treat the flash drive as if it were a memory card.
