Defines
#define	MSDD_STATE_READ_CBW   (1 << 0)
	Driver is expecting a command block wrapper.
#define	MSDD_STATE_WAIT_CBW   (1 << 1)
	Driver is waiting for the transfer to finish.
#define	MSDD_STATE_PROCESS_CBW   (1 << 2)
	Driver is processing the received command.
#define	MSDD_STATE_WAIT_HALT   (1 << 3)
	Driver is halted because pipe halt or wait reset.

	Driver is starting the transmission of a command status wrapper.
#define	MSDD_STATE_WAIT_CSW   (1 << 5)
	Driver is waiting for the CSW transmission to finish.
#define	MSDD_STATE_WAIT_RESET   (1 << 6)
	Driver is waiting for the MassStorageReset.
#define	MSDD_STATUS_SUCCESS   0x00
	Method was successful.
#define	MSDD_STATUS_ERROR   0x01
	There was an error when trying to perform a method.
#define	MSDD_STATUS_INCOMPLETE   0x02
