Comments
Setup sets the value of DEVPKEY_Device_Address to the address of the device on its bus. For information about the interpretation of a device address, see the DevicePropertyAddress value of the DeviceProperty parameter of IoGetDeviceProperty.
You can call SetupDiGetDeviceProperty to retrieve the value of DEVPKEY_Device_Address.
Windows Server 2003, Microsoft Windows XP, and Windows 2000 support this property, but do not support the DEVPKEY_Device_Address property key. Instead, you can use the corresponding SPDRP_ADDRESS identifier to access the value of the property on these earlier versions of Windows. For information about how to access this property value on these earlier versions of Windows, see Accessing Device Instance SPDRP_Xxx Properties.
