How to get port status of USB hub

Hi, Everyone,

Does anyone know how to get the information (such as, LS/FS/HS device
attached, Over-current and etc) on port status of a USB Hub from a filter
driver or client driver or user-mode application.

If we have got the symbolic name of the hub from application, any idea on
how to get the corresponding hub’s PDO from this symbolic name?

Thank you in advance for your help!

Regards,

Shunnian

In the NT DDK is source for USBVIEW. This program gives all the information
you probably want. It is a user mode app.
