Change 129302 by hselasky at hselasky_laptop001 on 2007/11/20 20:25:10

	
	A pointer to a structure of type "struct usbd_page_cache" will
	be passed to the "bus_dmamap_callback_t" function. To be able
	to start the USB transfer after loading the DMA we need a back
	pointer to the USB transfer. This commit adds this back pointer.
