I need to gather the PLD (Physical Location Device) information for every USB port on the system. So, to achieve that, I can call the _PLD method for every USB Root Hub. What’s the best way to do that? I don’t know much, but a filter driver for USB Root Hubs could solve the problem? Is this a good way to do that?
You don’t need a driver. The PLD information is surfaced as a property on each of the usb hubs that report this information. In user mode, you enumerate each hub and then query for the property.
