  17 General Description:
  18 This file is an example configuration (with inline documentation) for the USB
  19 driver. It configures V-USB for USB D+ connected to Port D bit 2 (which is
  20 also hardware interrupt 0 on many devices) and USB D- to Port D bit 4. You may
  21 wire the lines to any other port, as long as D+ is also wired to INT0 (or any
  22 other hardware interrupt, as long as it is the highest level interrupt, see
  23 section at the end of this file).
