Hi,

I am currently developing a USB driver that should support win2k and
winxp.

My questions is if i have to create two different drivers built with
the OS specific include directories in the DDK. Or can i choose for
example to use all includes from xp directories and then run that
driver on win2k as well without any worries. This is how i am doing it
right now, and it works, im just wondering what the correct approach
would be?

Regards
Wilhelm Lundgren

In this case it's better to build a driver for w2k platform.

Thanks for the answer,

Why is it better in this case? What cases are ok ?

WinXP has more more expanded api then w2k. Therefore it will be possible
that a driver will have a call of function which does not exist in w2k.
And the call of such function can be implicit, for example from code of
statically linked system libraries or from inline api functions.
But if your driver, which has been built under wxp, successfully works
on w2k platform then it is possible to use it.

And since KMDF 1.1 supports 2000 you should use it for driver development.

I would create w2k binary only, it will run fine on XP and 2003.
