One other thing you could try is to physically disconnect and then reconnect the
USB tower from the system. I've found that (on Win98 at least) the driver
sometimes freezes up and won't open until after I do that little dance.
Also, you could try running my MSGMON program (complete with source code) to see
if it works for you. I use pretty much that same CreateFile() call that Mark
quoted earlier in this thread.

Hope this helps!
