The subject behavior may occur if you chain devices together that use the IEEE 1394-1995 standard and the newer IEEE 1394-2000 standard on the same IEEE 1394 BUS or HUB. When you power on an IEEE 1394-2000 device, Windows XP optimizes the gap count for all devices that are chained together, which triggers a reset of the IEEE 1394 bus. This may cause some IEEE 1394-1995 (older) devices to be incorrectly enumerated.
To workaround this problem, use either of the following:
• Power off the device that is NOT working and power it back on.
• Disconnect the device that is NOT working and re-connect it.
• Disable and then re-enable the 1394 host controller:
• Expand the IEEE 1394 Bus host controllers in the device tree.
• Right-click the IEEE 1394 Bus host controller and press <b>Disable</b>. Press <b>Yes</b> if prompted to verify.
• Right-click the IEEE 1394 Bus host controller and press <b>Enable</b>.
• Exit <b>Device Manager</b>
