def __init__(self, *args, **kwargs):
        self.ws_class = kwargs.pop('ws_class', WebOSWebSocketClient)
        super(InputControl, self).__init__(*args, **kwargs)

def get_control(self, controltype):
        if controltype not in self.clients: 
            if controltype == 'media':
                control = MediaControl(self.client)
            elif controltype == 'input':
                control = InputControl(self.client)
                control.connect_input()
            elif controltype == 'system':
                control = SystemControl(self.client)
            elif controltype == 'source':
