De-populate the 0-ohm resistors connected to "U2A_GPIOx" and "U2A_3V3"
nets before attaching the External USB2ANY module to the USB2ANY Header.

LAYOUT NOTE:
Place 0-ohm footprints close to USB2ANY Header pins to minimize trace stubs
when 0-ohm resistors are de-populated (to disconnect the on-board MSP430).
