title: Can .inf file reference a built-in driver such that it won't give warning during installation?
body: <p>Our device relies on a built-in windows driver (usbser.sys). Do we still need to go through WHQL testing or can we install in such a way that the user won't see a warning about not passing Logo testing? I found <a href="http://support.microsoft.com/kb/837637" rel="nofollow">http://support.microsoft.com/kb/837637</a> but it's not clear to me if this will do what I want. Does it matter whether I use DPInst program or have my own program that calls DriverPackagePreinstall?</p>
