This backend can be used to intercept events from a joystick device if the device does not work with the standard

:class:`platypush.backend.joystick.JoystickBackend` backend (this may especially happen with some Bluetooth

joysticks that don't support the ``ioctl`` requests used by ``inputs``).

This backend only works on Linux, and it requires the ``joystick`` package to be installed.

|

nor :class:`platypush.backend.joystick.JoystickLinuxBackend`.
