You have to write a gadget driver: use the pxa2xx_udc controller driver (which talks to the hardware and handles all the hardware access stuff), on top of that you should write something that implements the specification for storage devices. Look at the existing gadget drivers (gadget_ether, gadget_zero) to see how things work... Robert -- Dipl.-Ing.
