Windows: How do you figure out the driveway that the system will download for the USB building?
-
There's a composite USB device, known Hub, and the port number where it's connected, can be accessed by descriptors. I'd like to know what driveway the system will load for each of the functions in this device. The list of GUID_DEVINTERFACE_USB_DEVICE via SetupAPI determines the path to the driver, but for the composite devices only the diver device is produced. Where to look?

A list of subsidiary devices can be obtained for composite devices using SetupAPI. https://docs.microsoft.com/en-us/windows-hardware/drivers/install/devpkey-device-children ) and remove their driver. The vault returns the list of InstanceID subsidiary devices separated by zero byte (REG_SZ_MULTI). Then we need to complete the list of all devices, filter the necessary InstanceID devices, and we can get a DVD.
Example of the code on C++ to remove the name of the driver, the way to INF-fail and the version of the driveway for all USB devices and their subsidiary devices:
