Due to addition of a dedicated device identification handler class all existing custom modules will have to be modified. The modification requires the straight forward change of the decorators.

t16000 = gremlin.input_devices.JoystickDecorator(

needs to be replaced with

t16000 = gremlin.input_devices.JoystickDecorator(
    gremlin.common.DeviceIdentifier(72331539, 2),

The benefit of this is that no matter whether or not you use duplicate devices the code is the same and it allows the implementation of a forthcoming feature.
