booting from usb ( AT91RM9200 PQFP)

hello ,

im using the AT91RM9200 PQFP package that does not have PIO D implemented. i want to boot the device from the usb port with the controller as the device and my PC as the host port. i cant figure out

where does the controller ROM boot uploader program look for the USB CNX signal on bootup on the PQFP package . The schematics for the AT91RM9200-DK fror the USB DEVICE INTERFACE shows the pin connected to PD4( which again is not available) , so how do i get to booting from the USB device ...is there a work around to follow or is the CNX signal not needed for DFU ?

Thanks in anticipation

MANAN
