The VFD I have is a VK202-24-USB and I'm running XPpro SP2
However theres a problem.

After a few tests it seems to do this only when the pc is cold booted, ie when it has been booted up after being switched off and unplugged from the wall socket. However if I restart the machine the VFD is detected fine. It is also detected ok if I shut down the machine and then physically turn it on again.
So to recap, this problem occurs when I turn the machine on after it has been turn off 'completely' from the wall socket.
Could someone please tell me why it is doing this? Its driving me nuts!!
