If you open Device Manager and right click on the device, properties, driver, there is an uninstall button. I believe if you hit that, you will be given the option to uninstall ALL drivers for the device. Maybe that would clean out the .inf file Windows is using and keep it from wanting to update. But I have not tried, and you will have to reinstall the drivers you want.
There may be an easier way, but I do not know what it migh be.
If Windows Update is loading the driver, you can set it so it will not install optional updates which will give you a chance to hide it first.
