If the above checks fail to find the root cause, then check the Windows security audit log and code Integrity event logs, described in the next section. If the service binary file copy has not been committed but the OS tries to start the service, the driver service will fail to start.

This eliminates an "unsigned driver" error message on install. This is, evidently, a driver developed by Microsoft. I saw reports that this and other drivers were signed in SP2 and this broke in SP3.
The goal is to do an install of the driver without a warning or error. Is this driver, or a compatible driver, available anywhere else? Is there a way to get it signed through WHQL? A company can choose to sign their own drivers rather than go through the WHQL testing process. File must be at least xpx and less than xpx.
