STM32F769 Discovery Board

I am currently trying to use the DFU mode on the STM32F769 Discovery Board. I have shorted a connection to VCC to pull BOOT0 to 3.3V (From Schematic R19). I have wired up PA11, PA12 and ground (Using USB pins) to the arduino connector on the board. Downloaded the DFuSe application. With BOOT0 tied to 3.3 V I reset the micro and the DFuSe doesn't seem to recognize the micro. Any insight to this would be greatly appropriated.

Most likely there are signals on other pins that the system loader is recognizing over going into USB mode.
