USB Superspeed Peripherals

Hello

We are currently attempting to pass the USB3 certification tests in a lab.

So far the tests passed for Windows10 64b & 32b.

But it fails for Windows7 64b & 32b.

We use the last Cypress SDK 1.3.4

Here is the message returned by the certification tool:

It is very strange because Driver and coinstaller were given by Cypress and they manage to get the Windows certification.

Thank you for your help

Hello Pascal,

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.

Best regards,

Hello,

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 ?

Thank you

Hello Pascal,

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.

Best regards,
