Yep, I looked at the code too and came to the same conclusion. Of
course, if Windows was open source, the driver could be compiled for the
platform and there would be no issues. Also, since most people don't
have the Microsoft ddk the binary driver would have to be distributed,
which is another negative.
Oh well. Still, if there was no other solution I would still consider
it.
