Command Verifier during UVC Descriptor Tests (Class Video Control
Interface Descriptor Test Video) compleins about:

Video Control Interface Header bcdUVC is 0x0100. USB Video Class
specification 1.0 has been replaced by 1.1 specification
(UVC: 6.2.26) Class Video Control Interface Descriptor bcdUVC is not 1.1

I assume this is a reference to a test case in the test suite.

It's a reference to UVC Compliance Test Spec.pdf. 
This document is part of Command Verifier tester.

I will resend the patch without typo.
