* version of the pullup.
* - No changes to jumper settings are required. There are few USB-
* related jumpers on the based board, but none are required:
* - J14 must be set to permit GPIO control of the base board USB
* connect pin. NOT USED
* - J12 must be set to permit GPIO control of the USB vbus sense pin
* - The standard VBUS (P1.30) is not connected. As a consequence, the
* USB driver will not correctly respond to USB insertion or removal
* events.
* - The standard USB LED (P1.18) is not connected.
