Has anyone used DFU ROM API on LPC546xx?

I have been trying to use the DFU feature in USB ROM API (Chapter 41 of UM10912). I followed the example for MSC and HID ROM to make my files (see attached). After calling USBD_API->hw->Connect(g_hUsb, 1), the device (connected at J3) is not visible to the host. I am using an LPCXpresso54628 board. All of the ROM API calls succeed, as much as I could verify. I have tried everything I could think of but I do not know what I did wrong. I also looked at LPCOpen-keil-lpc43xx/main.c at master · micromint/LPCOpen-keil-lpc43xx · GitHub and the code there looks similar to mine. Any suggestion on what to test or change is greatly appreciated.
