Arduino DUE Circuit JTAG Pullup resistors

Hi!

Why are the Pullup resistors for the JTAG in the DUE Circuit called RN1D, RN1A..... are they not placed? I don't have one here, so it would be nice if anyone could have a look on their boards :slight_smile:

Also, I plan to use the USB port, but only the Data Connection (and GND of course). In the Atmel Circuit Checklist it says to all the USB Ports "If USB Device is not used it can be left floating.".
Is there any sense connection on the VBUS pin to turn the USB connection ON/OFF?

RN = resistor network. The spare units of each network are simply
connected to ground. The routing means two networks each 1/2 used
was better than one fully used as far as I can see.
