Unique Identification of a particular device type

Question

Win32_PnPEntity class has so many properties but I want to know that is there any property which identifies the type of device uniquely . For example I have a fingerprint scanner device and its device id is something like this "USB\VID_0A86" but as per my understanding it will be different for a device with different vendor. I want to know the property whose value is same for all type of fingerprint scanners. Similarly same scenario for all webcams.

Answer 1
