Return the status for the specified recipient.

    dev is the Device object to which the request will be
    sent to.

    The recipient can be None (on which the status will be queried
    from the device), an Interface or Endpoint descriptors.

    The status value is returned as an integer with the lower
    word being the two bytes status value.

Return the specified descriptor.

    dev is the Device object to which the request will be
    sent to.

    desc_size is the descriptor size.

    desc_type and desc_index are the descriptor type and index,
    respectively. wIndex index is used for string descriptors
    and represents the Language ID. For other types of descriptors,
    it is zero.

Get the current active configuration of the device.

    dev is the Device object to which the request will be

    This function differs from the Device.get_active_configuration
    method because the later may use cached data, while this
    function always does a device request.
