Need to know more about 1394 in Windows-7?

The 1394 bus driver was rewritten for Windows 7 to provide support for higher speeds and alternative media, as defined in the IEEE-1394b specification. The 1394 bus driver that is included with Windows 7 replaces the 1394 bus drivers that were included with earlier versions of Windows. This paper provides information about the differences between the new 1394 bus driver implementation and the earlier implementation, as well as information about the new functionality that is included in the 1394 bus driver for Windows 7.
