A simple way to get VID and PID would be to load the devices INI file from %WINDOWS%\System32, I think that is where the INIs are usually copied. If you know the name of the INI file then it is trivial. If you are looking for a programmatic method, you can enumerate the USB bus using the Win32 Setup API.

If you have installed the Wnidows Driver Kit on your machine, take a look at the USBVIEW sample application. It demonstrates how you can enumerate the USB bus and get a list of all devices including their PID and VID.

To get the serial number, look at the GetVolumeInformation() system call.
