XP Service Pack 2 Breaks FireWire

Diluted writes "FireWire Depot is reporting about a problem with Service Pack 2 for Windows XP. Apparently not liking the competition from 1394b, Microsoft decided to limit S800 devices to a quarter of their speed capability."

Fixed with patch

Patch? Fix?

[Diluted]

Not fixed in a patch or released as a hotfix, but their 'fix' is for the person affected to edit their registry. Your average user is not going to want to edit their registry.

As far as the competition angle... USB is intel's protocol, firewire is largely driven by apple... that was my point about competition.

The real issue here is taht Ms's monopoly allows them to crush a protocol if they so desire.

and this is news?

Win XP SP2 "turns Firewire 800 into Firewire 100"

Oops a daisy

By INQUIRER staff: Wednesday 11 August 2004, 09:55
THE MODERATOR of the RME forum has warned that installing Windows XP SP2 can lead to the bus speed being limited to 100Mbit/s.

Matthias Carstens posted the message on the RME forum yesterday, but says it's not a problem particular to RME products. He said: "It affects any Firewire 800 device. If you have a FW800 PCI card and an FW 800 hard disk, go see the bits come one by one through the Firewire cable".

RME, he said, was aware of the problem for some time, but "didn't really imagine that Microsoft would have the guts to try to bury an existing standard. We just downloaded the final public version and it is simply unbelievable".

He said that some companies are trying to sell Firewire 800 drivers so everything will be hunky-dory. But, he said, these drivers probably won't work correctly with a Fireface 800.

But phew, there is an answer. He said after the SP2 update, if you install the old SP1 Firewire drivers all will be well. "In our tests this solved all problems and brought back the old performance and compatibility".

He said RME will release detailed instructions on how to do this today.

Could someone clarify? Registry hack or patch?

Could someone clarify?

I thought the problem with Firewire was resolved with a patch [microsoft.com]. But the resolution also mentions a Registry hack.

However, the Download page does not mention any registry hack [microsoft.com].

Is this problem fixed by the patch, or by a registry hack? Either? Both? Neither?

From the Microsoft link for the update: After, you install this update, if you add a host controller for a new 1394 device to your computer, you must add or modify the SidSpeed entry in the Windows registry for the new 1394 host controller. To do this, follow these steps:
