//Generic device callback

    //example for cascading hubs, we need to the hub from the port is is
    //connected to, in addition to the port
    if (event == LIBUSB_HOTPLUG_EVENT_DEVICE_ARRIVED)

    //Multiple callbacks can be called multiple times, so it makes little sense
    //to register a separate ykush callback, when we anyway have to filter here
