title: HCK USB-IF Certification - No Passing USB20CV CH9 Test
body: <p>I'm trying to certify a USB device and I pass every test but the USB-IF Certification Validation Test(Device)</p>
  
  <p>I run the "USB 3 Gen X CV" and pass the 2.0, chapter 9 tests.  I then take the 3 files and move them to c:/usblogs (I'm using the client machine to run USB-IF tests).</p>
  
  <p>But I recieved the "No Passing USB30CV CH9 Test for USB2.0 logs found for the specified device" message.</p>
  
  <p>Then I found this post about renaming the files: <a href="https://social.msdn.microsoft.com/Forums/windowsdesktop/en-US/3227a1b0-069e-4593-9861-18d66f9dca72/usbif-test-results-log-file-format?forum=whck#e134fca5-e164-4d8c-8875-2dc2d66b9232" rel="nofollow">https://social.msdn.microsoft.com/Forums/windowsdesktop/en-US/3227a1b0-069e-4593-9861-18d66f9dca72/usbif-test-results-log-file-format?forum=whck#e134fca5-e164-4d8c-8875-2dc2d66b9232</a></p>
  
  <p>But that didn't work.  I also have a previous submission to look thru and noticed that it used to produce a .log file instead of .bak.  I tried just renaming but no luck.</p>
  
  <p>I tried finding older versions of USB30CV but to no avail.</p>
  
  <p>I also tried to run USBIFValidation.exe manually and see what fails but it exceptions for not finding "Vex.Logger.Interop".  </p>
  
  <p>Using Windows 8.1 64 </p>
  
  <p>Could really use the help!  Not sure what else to try.  Sorry, not enough rep to post my pictures...</p>
