We don't really support USBHOSTLITE.

Have you considered using LPCOpen Platform for this part? (http://www.lpcware.com/content/nxpfile/lpcopen-software-development-platform-lpc17xx-packages)
There is a host mode Mass Storage example in there which we do support. This example uses ChanFS which is a very comprehensive open source FAT driver that should do everything you need.
