How to stop reloading the driver when the USB device is plugged i n same slot ?

Hi all,

I have a question about how to stop reloading the same driver in windows
2k/xp environment . The firmware does not send any serial number in its
descriptors . I believe that when the device is not sending any serial
number , the OS should not ask for driver again as if it is a new device .
what makes OS to think that this is a new device ? Anybody has any idea how
to solve this problem ?

thanks in advance
