The D+ & D- USB pins of that chip are RC5 and RC4, so these can be accessed via the PORTC E-Block connector or via the header blocks next to the chip sockets (see the datasheet for the pinout).

It is likely you will not need to connect Vdd to the usb socket (unless you want to power the whole of the board via usb, but this can be tricky and I would not suggest you did this).

You will need to connect the ground pin of the USB port to the development board.

fantastic!!
thanks for the help im going to experiment now hehe
