Hi. As stated in the thread title, we are currently running version 6.7.4.0 of the usbuart driver through certification with our INF modifications but it has failed the Device Guard test. I understand this test is somewhat new and this driver version went through certification late last year or early this year, I think. Did the unmodified version pass this test or was it not in place at the time? And is there a way we can massage the driver into passing? The message I received from the lab is below:
We have a failure on the 64 bit driver. The driver is not compatible with Windows 10 Device Guard.
WDTF_TEST : Non-zero Code Integrity statistic found: Execute Pool Type Count: == 8
WDTF_TEST : Non-zero Code Integrity statistic found: Execute-Write Section Count: == 1
Please see https://blogs.msdn.microsoft.com/windows_hardware_certification/2015/05/22/driver-compatibility-with-device-guard-in-windows-10/ for information on how to test your driver for device guard compatibility.
