Remarks
Windows sets the value of DEVPKEY_Device_UINumber to the value of the UINumber member of the DEVICE_CAPABILITIES structure for a device instance. The bus driver for a device instance returns this value in response to an IRP_MN_QUERY_CAPABILITIES request.
You can call CM_Get_DevNode_Property or SetupDiGetDeviceProperty to retrieve the value of DEVPKEY_Device_UINumber.
Windows Server 2003, Windows XP, and Windows 2000 support this property, but do not support the DEVPKEY_Device_UINumber property key. Instead, you can use the corresponding SPDRP_UI_NUMBER 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.
Requirements
Version: Windows Vista and later versions of Windows Header: Devpkey.h (include Devpkey.h)
