you might cross-reference port_#x.hub_#y output of usbview. i've used tool numerous times information existing usb tree.

the usbview sample available in wdk. if unfamiliar this, run - tool walks entire usb tree on system , prints out information , descriptor listings each device, locations on host controllers , hubs.

start @ refreshtree() function in sample, can follow code see how enumerates host controllers, hubs , devices.

the easiest way source sample install 7.1.0 wdk available here: http://www.microsoft.com/en-us/download/details.aspx?id=11800
