While the LPC1769 has a USB Host peripheral, it is USB Full speed, so it will be a very slow MSD.
consider the LPC1800 which has a high speed USB phy.
there are application notes that show one how to interface a USB Host connector to the LPC product line.
you will have to do some homework, after all, if it was easy, it would not be called engineering.
