  No, I'm afraid that won't work, because only /dev/sda ... /dev/sdz exist by
default.  "mknod" doesn't work on cygwin the same way it works on *nix: yes,
it creates a special file representing a device, but there is no kernel to
translate special device major/minor numbers into actual hardware devices.

  The sources that I pointed you at are the only connection between files and
devices on cygwin, and you do need to modify them.  However, it is simple and
reliable, so you should not worry about using the technique; you're only doing
what the cygwin dll already does, just for more device names.


    cheers,
