  15   To adapt the bootloader to your hardware, you have to modify the following files:
  16   - bootloaderconfig.h (this file):
  17     Define the condition when the bootloader should be started and the initialisation of the
  18     hardware
  19   - usbconfig.h:
  20     Define the used data line pins. You have to adapt USB_CFG_IOPORT, USB_CFG_DMINUS_BIT and
  21     USB_CFG_DPLUS_BIT to your hardware. The rest should be left unchanged.
