  Support for DFU Upload mode of the DFU automaton. The host is
  able to request firmware upload from the device and get back the
  device firmware content.
  WARNING: this feature is a standard DFU function but generates a
  security breach. Activate it only if you know what you do.

  ---help---
  Support for DFU Download mode of the DFU automaton. The host is
  able to flash the device firmware through DFU with a new firmware
  image. This option allows the DFU automaton to accept DFU download
  requests but is not responsible for correct firmware image handling
  (new firmware authentication, integrity, and so on).
