Windows 10: Firewire port issues. Failure again on windows 10

Hi, I use a Firewire audio interface on Windows 10 Pro. the 1394 driver installed was a legacy driver released by Microsoft as a turnaround to solve firewire issues in windows 10. After some Win 10 update it simply stopped to work , but it is still recognized by Device Manager, and shows ok. Sometimes after boot it works for some minutes or seconds , them stops and do not see the audio device anymore. I also replaced the IEEE1394 card with another with different chipset, now Texas. The old is VIA. Same problem. Then i installed the devices on a windows 7 computer and all things are working aga

FireWire Malfunction

I have an old video camera that requires a firewire. I've had two different firewire to USB ports saying that they have both malfunctioned within the seconds of inserting them into my computer. I've downloaded the IEEE 1394 Legacy ports and done them step
by step but to no avail. Nothing seems to work and it keeps saying that it's malfunctioned. Please help!

 

Does Windows 10 Pro x64 support Firewire adapter?

I learned Windows 10 does support firewire. A 3 port firewire 1394B & 1394A PCIe card
adapter was installed and sure enough, the system does recognized the device. The device manager lists the firewire adapter as, "Texas Instruments 1394 OHCI Compliant Host Controller." The firewire device supports both 800 or 400 Mbps. A
HD camcorder (Canon HV20) connected to either 1394a or the 1394b port and was tested, both 1394a and b worked.




So to answer my own question, yes, Windows 10 supports firewire.

 

20H2 and Firewire/Audio issues

I have a MOTU Ultralike MK3 which I have connected through Firewire on my desktop.

My specs:

• ASRock B450M-HDV R4.0 Motherboard
• AMD 3800X
• 32 Gb DDR4
• Vantec PCIe Firewire interface with Ti chipset

Before my upgrade to 20H2 - my playback was quite stable but since this upgrade, I'm getting a bunch of weird playback glitches. That is not even under load. I just play a file in JRMC with the ASIO interface and I get multiple drop-outs glitches. The playback
definitely stops for 1 sec or so, there is no level showing up anymore during that second on my audio interface.

I changed two times already the firewire cable, and the firewire card as well.

My bios doesn't have a lot of options and I have the legacy 1394 driver installed which used to work quite nicely.

Any suggestions?
