Windows sets the value of DEVPKEY_Device_BusTypeGuid to the value of the BusTypeGuid member of the PNP_BUS_INFORMATION structure that a bus driver returns in response to an IRP_MN_QUERY_BUS_INFORMATION request.
You can call CM_Get_DevNode_Property or SetupDiGetDeviceProperty to retrieve the value of DEVPKEY_Device_BusTypeGuid.
Windows Server 2003, Windows XP, and Windows 2000 support this property, but do not support the DEVPKEY_Device_BusTypeGuid property key. Instead, you can use the corresponding SPDRP_BUSTYPEGUID 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.
