usb mass storage device in arm lpc2388

Hi,

I am trying to get the sd card which is connected to the SPI Port of my controller to be read as a mass storage device.  But before that I just try by using a USBMem code example from keil (original code for RAM). When I connect a usb cable to my pc, it shows usb device is not recognize but in usb controllers it shows unknown device. Can anyone suggest what I am missing.
