Webcam Driver coding

So i have an old webcam which has drivers that only support win xp. It isn't just any webcam, it has this very nice night vision thing with IR leds so i wont be buying a new one.

So i thought about making the driver myself but couldnt find any tutorials and i dont have any idea how to write driver for webcam. If someone has tutorials for this or can help me with this i would be grateful. Thanks.
what cam model it is?
Logitech quick cam
thats the whole series. Give me model number/name. I cant believe there is no working solution for win7.
Logitech QuickCam Messenger is the full name i think.
Thre is no solution for win7 as far as i have searched and asked around.
