# digitalbitbox hardware module
#

      Digital Bitbox provides dbb-app, a GUI tool, and dbb-cli, a CLI tool, to manage Digital Bitbox devices.

      This package will only install the dbb-app and dbb-cli, however; in order for these applications to identify and access Digital Bitbox devices, one may want to enable the digitalbitbox hardware module by adding

          hardware.digitalbitbox.enable = true;

      to the configuration which is equivalent to adding this package to the udev.packages list.


      The easiest way to use the digitalbitbox package in NixOS is by adding

          programs.digitalbitbox.enable = true;

      to the configuration which installs the package and enables the hardware module.
