Re: USB I/O

["Marin David Condic" <mcondic.auntie.spam@acm.org>]

I have not done this yet. (Day ain't over, yet!) However, I'd suggest this:
Whatever is happening at either end of the USB port, you've *probably* got
some kind of OS calls to deal with it. Either it looks like a file (in which
case, one of Ada's I/O packages - probably Streams - is the way to go) or it
looks like something completely different (in which case, there's got to be
some custom OS services to handle it and you just connect to them using
Ada's ability to interface to other languages.)

If you don't have an OS and you're trying to write low level driver code,
then your first stop is the hardware reference manual for the device you're
looking at. Somewhere between that and the hardware reference for the
machine you're using, you should be able to figure out how to write code for
the device.

If you need more help, you ought to post more details. Explain what your
target hardware and OS look like and identify the particular compiler you're
working with. You might explain what you're trying to do with the USB and
what overall approaches you are investigating (OS calls, file I/O, bare
machine, etc...)
