Ada binding for USB ports on Windows 95?

Ada binding for USB ports on Windows 95?

[Bob Spooner]

Does anyone know of such a binding or, lacking that, a source for the 
specifications for the C interface so I can write my own?

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.

I was thinking XP and for some reason wrote 95.

USB 2 is what I need. Thanks.

if you intend to build an interface, libusb is a good place to start.
it is also intended to be platform independant.

hope this helps, srini

Thanks Srini. That looks interesting.
