Where can i find a list of "Microsoft OS Descriptors" for USB?

I am tr开发者_运维知识库ying to find a list of "Microsoft OS Descriptors" for USB.

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.

Any ideas?
