 ***   FIXME FIXME FIXME FIXME
 ***
 ***   A bunch of board-specific #defines that are only used by the
 ***   USB routines got put into libmaple.h for what appear to be
 ***   historical reasons.  I'm [mbolivar] putting them in here for
 ***   now, so that we can treat the usb/ directory as a black box,
 ***   freeing the rest of libmaple/ to be implemented as a
 ***   general-purpose STM32 library. All of this REALLY needs to get
 ***   moved into wirish when we get a chance to redo the USB stack.
