Once a control point has discovered a device its next step is to learn more about the
device and its capabilities by retrieving the device's description from the URL provided by
the device in the discovery message. After a control point has retrieved a description of
the device, it can send actions to the device’s service. To do this, a control point sends a
suitable control message to the control URL for the service (provided in the device
description).
When a device is known to the control point, periodic event notification messages are
sent. A UPnP description for a service includes a list of actions the service responds to
and a list of variables that model the state of the service at run time.
If a device has a URL for presentation, then the control point can retrieve a page from this
URL, load the page into a web browser, and depending on the capabilities of the page,
allow a user to control the device and/or view device status.

UPnP is currently only supported by this switch for Windows Vista, but will supported for
