C specifications can be found in the MSDN. For example HID USB devices:

   http://msdn.microsoft.com/en-us/library/ms790932.aspx

I doubt that there exist Ada sources, for all the API is catastrophic. For
example, to catch device connect/disconnect notifications you need a
window! They are sent as window message!

As for C. You can find some C++ code here:

   http://lvr.com/hidpage.htm#MyExampleCode

Beware, if I correctly remember, the code is not very good (contains
superfluous calls, maybe, even leaks resources, I don't remember the
details, sorry. So carefully read Microsoft description of the API
functions the code uses. You will easily figure out its weak points.

P.S. I cannot tell anything useful about Windows 95. AFAIK, it did not
fully support USB.
