Firewire (IEEE1394) and USB2.0 Problems
The USB device does not work
• Windows NT 4.0 does not support USB protocols.
• Check the settings in the Windows Control Panel.
• Make sure you have installed the necessary device drivers.
• Contact the device vendor for additional support.
The IEEE1394 port does not work
• Go to [Start > Settings > Control Panel > System > Hardware > Device Manager].
You should see an entry which reads “Texas Instrument OHCI Compliant
IEEE 394 Host Controllers”. If it does not exist, Windows has not detected the
host controller or the device driver has not been installed properly. If there is
a yellow mark or red cross on the 1394 host controller, it may be a device or
resource conflict. Replace or update the device driver from the factory CD-
ROM disk or consult the Windows manual on how to solve the resource
conflict problem.
• Make sure the cable is fully connected.
• Make sure you have installed the necessary device drivers.
• Contact the device vendor for additional support.
