It’s not clear to me whether this is a problem in the USB class driver or in 
your descriptor.

If the former, the appropriate mitigation for the test failure is for Microsoft 
to issue an errata, since the bug is in the OS.

If the latter, you should fix your descriptor.

Can you send me a screenshot of your KS filter in KS Studio, and your 
descriptor? I’m particularly interested in the terminal type of the pin in 
question.
