I had a problem with Windows XP Pro SP2 recognizing all of the 1394 devices
that I had installed in my computer. Fortunately I had a 3 output 1394 board
installed, and connected each 1394 device to its own connector. Now all of my
3 1394 devices are recognized and work fine. In you case, it may be that it
is not working in a "Daisy Chain" type of connection.
