Hi,

This is all about USB Vendor ID and Product ID. I am working USB mass
storage devices.

I have used msinfo32 to get the USB vendor ID and Product ID and some
strange numbers follow after the product ID.

Questions
[1] How does this Vendor ID and Product ID work ?
[2] What makes the USB mass storage device hardware unique from each ?
[3] Is it possible to have same PnP Device ID for two USB mass storage
Devices ?


All relevant answers will be appreciated.
