  default n
  ---help---
  libxDCI allows to handle some variations between FW and DFU mode, making DFU and FW
  libxDCI footprint, performances, debug levels dedicated to each mode.
  This simplifies the stack debugging, reducies the needed storage content to the one
  requested in the given mode, and make USB informations (product name, device name and
  so on) being mode-specific.
