USBD_RegisterHcFilter routine

The USBD_RegisterHcFilter routine has been deprecated in Windows XP and later operating systems. Do not use.

On Windows XP and later operating systems, a filter driver that is installed between the root hub FDO and PDO sees all USB traffic for a USB device after it has been enumerated. There is no supported mechanism for filtering descriptor requests that occur during the enumeration of a USB device, because those requests originate and remain in the port driver (usbport.sys) and not the hub driver.

);

Parameters
