      public static Quintet<java.util.Set<java.lang.Integer>,​java.util.Map<java.lang.Integer,​java.lang.Integer>,​java.util.Map<java.lang.Integer,​java.lang.String>,​java.util.Map<java.lang.Integer,​java.lang.String>,​java.util.Map<java.lang.Integer,​java.lang.String>> queryDeviceTree​(com.sun.jna.platform.win32.Guid.GUID guidDevInterface)
      Queries devices matching the specified device interface and returns maps representing device tree relationships, name, device ID, and manufacturer
      Parameters:
      guidDevInterface - The GUID of a device interface class for which the tree should be collected.
      Returns:
      A Quintet of maps indexed by node ID, where the key set represents node IDs for all devices matching the specified device interface GUID. The first element is a set containing devices with no parents, match the device interface requested.. The second element maps each node ID to its parents, if any. This map's key set excludes the no-parent devices returned in the first element. The third element maps a node ID to a name or description. The fourth element maps a node id to a device ID. The fifth element maps a node ID to a manufacturer.
