Consider the following scenario:
- You connect a device to a Microsoft Windows XP-based computer by using an Institute of Electrical and Electronics Engineering, Inc. (IEEE) 1394 (FireWire) connection.
- The device uses the High Definition Audio-Video Network Alliance (HANA) specification.
In this scenario, the connected IEEE 1394 device does not recognize the computer. For example, a connected TV that uses the HANA specification shows other connected IEEE 1394-based devices on the screen. However, the connected Windows XP-based computer is not listed.
The problem occurs because of a bug in the Windows XP IEEE 1394 bus driver (1394bus.sys).
