Can you please elaborate on what errors you are seeing with DPTF.
Does it present a yellow bang in the device manager after deployment? Does it not fix if you try to manually point to the INF file and try installing the driver through device manager. If yes for both, what is the error code you see in the device manager. Right-click on the driver (yellow-bang) -> Properties and see error code under "General" tab. Please share the same here.
