Hi Bulat,
(...)
Thus my cry for help explicitly to Haskellers on Windows.
(...) It's a pitty that Windows receives so little support, but I guess if nobody has a Windows box to test with, there's not much you can do about it.
I think it deserves consideration: what about a mailing list like haskell-portability? If someone asks on this haskell-cafe for some way to do, say, USB on windows using Haskell, some answers would arrive; but if one asks at this, say, haskell-portability list, "I have a working Haskell USB library running everywhere except on Windows", it's likely to get the attention of people who do have deep OS understanding and are willing to do a big effort to solve a problem if that results in a new library that can be trusted at any OS.
