DP is on TP14
DN is on TP16
ID is on TP4
these testpoints are not marked, but TP14 and TP16 are right under the USB connector. TP16 is the one closer to the board edge. TP4 is the square pad located close to the keepout zone that contains the text H49904-002, almost at the other end of the board. I had trouble finding test points until I downloaded Allegro Free Viewer so I could open the .brd file that contains the layout.
I include top and bottom layout, perhaps someone find a use for the pictures.
