Pins 12 and 13 of the ATxmega64 are D- and D+ respectively, according to the datasheet.
I think that one could use the schematics for an arduino with the ATmega16U2 chip USB interface, as an example of connections of D- and D+ between the microcontroller and the connector. I have followed those schematics to build a usb to ttl converter using the 16u2.
Wikipedia, I notice, shows the pin assignments for the micro USB B connector in their USB article.
