For a present device, the DEVPKEY_Device_Parent property will provide you the device instance ID of the parent of that device. For a non-present device:
- On Windows 8 and later:
- If the parent of the non-present device from the last time the non-present device was a present device still exists as a device on the system (present or non-present device), DEVPKEY_Device_Parent will provide the device instance ID of that parent device.
- If the parent of the non-present device from the last time the non-present device was a present device does not still exist as a device on the system, DEVPKEY_Device_Parent will return the device instance ID of the device that is at the root of the device tree.
- Prior to Windows 8:
- Retrieving DEVPKEY_Device_Parent will return an error that the property is not found.
