Windows - How to explore the devices by connection. Like Windows "Device Manager"

The idea is to start from the VID and PID of USB hub and then explore its contents.

Given a USB hub how do we explore the 开发者_开发知识库connected devices?

I need to programmatically explore the attacked devices to a USB hub, some of these devices can be "USB Composite Device".

I'd like to do as "Device Manager":

I tried run some queries with WMI, but I did not get any result.

PS: My reference language is C#.
