[Libusb-devel] Number of ports of USB controller

[Ganesh_Borse@Dell.com]

Hi,

I am developing an application on Windows 2000 to access USB devices.

I would like to know the number of ports connected to USB root hub as well
as any other USB hubs connected to ports of USB root hub.

I tried to search this information in registry (
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\USB\ROOT_HUB), but I did
not find any entry for number of ports.

I tried with WMI browser also, but it also does not give this information.

May you please guide, where can I find this information?

Thanks,
Ganesh
