Please let us know the timestamp of the Digital Signature of the WdfCoInstaller01011.DLL file and the WUDFUpdate_01011.DLL file in the below path.
C:\Program Files (x86)\Windows Kits\<WDK Version>\Redist\wdf\<Architecture>
The version timestamped at 2012/07/26 is a buggy one and was replaced with a newer version with the timestamp as 2012/08/17.
I had a look at dll in Windows Driver Kit (WDK 10) in folder C:\Program Files (x86)\Windows Kits\10\redist\wdf\x64 : Here are the timestamps
- WdfCoInstaller01011.DLL is 2012/08/17
- WUDFUpdate_01011.DLL is 2012/08/17
-> So it seems these are the good versions, so we will take this WdfCoInstaller01011.DLL
-> Concerning WUDFUpdate_01011.DLL, in your Cypress v1.3.4 SDK, you were only provided WdfCoInstaller01011.DLL with the driver,
so do we also have to provide WUDFUpdate_01011.DLL which is in C:\Program Files (x86)\Windows Kits\10\redist\wdf\x64 ?
Sorry for mentioning the WUDFUpdate_01011.DLL. The CyUSB3 driver only requires the WdfCoInstaller01011.DLL file. Please use the latest version and check if the test passes.
