Why USB0 works, but USB1 does not work on HID LPCOPen project?

I am using code (NXPLPC1837/ NGXLPC1830xplorer)  from below site

LPCOpen Software for LPC18XX|NXP 

for NGX LPC1837 xplorer board.

However , in HID class keyboard project, only USB0 is enumerated as HID class device (keyboard). But  I wanted to use both USB0 and USB1 as HID class device.

In app_usbd_cfg.h it is written USB1 can be used instead of USB0 , by commenting  #define USE_USB0 and uncommentiing #define USE_USB1. However, it didnot work.

Can you please help me on solving this problem?
