Device Relations Properties
In Windows Vista and later versions of Windows, the unified device property model supports device instance properties that provide information about the parent, child, and sibling devices of a device instance. These properties are listed in this section by their corresponding property keys in the unified device property model.
The following information is provided about each device relations property:
The property key that represents the property.
The property-data-type identifier that indicates the data type of the property.
Whether a property is read-only.
Whether the property value is localized.
How to access the property.
Windows Server 2003, Microsoft Windows XP, and Windows 2000 support these properties. However, these earlier versions of Windows do not support the property keys in the unified device property model. Instead, these earlier versions of Windows use different mechanisms to represent and access the properties. The information that is provided with each property key indicates which earlier versions of Windows support the property and provides a link to information about how to access the property value on these earlier versions of Windows.
