I am doing Windows 7 HCK testing on a USB audio driver.
One of the tests fails with this error:
....
Message 7-1-2019 2:06:50.887  authParam.NumFailures = 5, expected at least 3
Message 7-1-2019 2:06:50.887  Failure condition: usbccgp.sys could not be detected in the list of expected failed drivers

 What am I doing wrong here?

Is this an actual USB device, or are you using a USB remoting solution, like USB-over-Ethernet?  Or, is this a USB 3 device? Windows 7 did not have USB 3 support, so whatever USB 3 driver stack you have was provided by the host controller manufacturer, not by Microsoft, and that means usbccgp.sys is not present.  If your computer has a USB 2 port, you should try plugging in your device there.
