title: Where can i find a list of "Microsoft OS Descriptors" for USB?
body: <p>I am trying to find a list of "Microsoft OS Descriptors" for USB.</p>
  
  <p>The best I could do is find a reference to "Appendix 1 of Extended Compat ID OS Feature Descriptor Specification". Of course I can not find this either.</p>
  
  <p>Any ideas?</p>
