The Felix UPnP base driver registers a non standard service implementing two interfaces:

org.apache.felix.upnp.basedriver.controller.DevicesInfo;
org.apache.felix.upnp.basedriver.controller.DriverController;

The former can be used to retrieve the XML description of both devices and services. Other than be used for debugging purpose, it allows access to the UPnP schema extensions defined by UPnP Vendors. According to the UDA 1.0 they consist of elements inserted in different points of the XML description and by convention starting with the prefix "X_". This interface is used by the context menu handler of the UPnP Tester bundle.

The latter interface can be used to change the log messages of the base driver at runtime. Two different methods are available to modify the log level of the base driver or to enable the visualization of low level messages related to the UPnP stack protocol (CyberDomo). Furthermore, the interface allows developers to send an M-SEARCH discovery message to the UPnP networks, thus refreshing the list of imported devices.

\[1\] Developers should monitor UPnpEventListener services with a filter matching either the own service Id or service type, either the own device Id or device type and even a empty filter which are usually used to express interest for every UPnP device.
