Windows 8.1 - Legacy Firewire Drivers

Hi Daniel,

Are you able to locate "legacy1394.inf" from the either location path below?

• C:\Program Files\1394 OHCI Compliant Host Controller (Legacy)\x86_driver
• C:\Program Files\1394 OHCI Compliant Host Controller (Legacy)\x64_driver

Can you specify which steps you are failing to execute? I want to understand whether this is MSI installation failture or device installation failure from INF file. See step by step from "Additional steps of configuration requirement" section in the KB articule.

Do many have experience with this driver yet?  I've installed it and it did indeed improve my issues - but it's still very 'quirky' and unreliable.  I have to 'fiddle' with buffer settings every time I boot up to make the dang thing work/sound right...

FYI: My Windows 8 Pro did not have the Legacy 1394 driver and I could not capture DV via Firewire.

When I upgraded to Windows 8.1 Pro from Win 8 Pro, I then saw the Texas Instruments 1394 OHCI Compliant Host Controller and can now successfully capture DV via Firewire.

I followed all the instructions in the above link, and the subsequent KB article.  The problem is that the download (x64) does not contain the specific files identified in the setup instructions.  First, after running the setup file the location of the distributed files is not where the instructions say they will be.  Second, the file that the instructions says to select from the Device Manager is not there.  The message from windows is that the driver files are up to date.  And yes I selected to option to choose the driver file from a location on my PC, and navigated to the location specified in the kb article instructions.  In fact once there I did not even have the option of selecting a specific file.  Only the folder containing the file.

For me the issue is not with video transfer but rather audio.  I have a recording studio and am entertaining the idea of using PC instead of the typical mac.  The experiment will soon be over if I can't get the firewire driver issue fixed.  Audio plays but it is scratchy.  Obviously not acceptable.
