1394 not recoginizing video camera

I am grasping at straws here, but could this knowledgebase article relate to
the non-recoginition of 1394-connected DV cams? What I'm asking is if the
speed being reset to S100 could impact device recognition on a 1394 port? Or
does that only have effect after connection with the device is established?

Performance of 1394 devices may decrease after you install Windows XP
Service Pack 2
SYMPTOMS
After you update your computer to Microsoft Windows XP Service Pack 2 (SP2),
the performance of your 1394a or 1394b FireWire devices may be greatly
decreased. A digital camera that uses S400 speed is an example of such a
device.

This problem occurs if you connect a 1394a or 1394b FireWire device to a
1394b port. This problem occurs because Windows XP SP2 changes 1394b ports to
S100 speed when you upgrade.

OK, so now I am even further confused!

Today I brought my DV camera and Firewire cable to the office. I plugged it
into a co-worker's Dell laptop 1394 port. Lo and behold, the camera is
recognized.

I then checked the O/S (XP SP2), and the 1394 driver (as loaded by XP SP2).

Why do you think the operation of 1394 driver is so system dependant?

LONE5RANGER,

I am hoping you might have some suggestions for me regarding my inability to
connect my Sony DVR-PC1 camera via 1394 adapter under WinXP. It is just
never recognized as being connected.

I have researched all the forums and boards, and tried everything that
others have had success with, to no avail.

I am running WinXP SP2. I have tried 2 different known good DV cables, 2
newly purchased 1394 adapter cards - one VIA based, the other TI based - I
have backed the 1394 drivers down to XP SP1 versions (ensuring that they are
not automatically updated to SP2 drivers upon boot). The VIA-based adapter
was a USB/1394 combo, on which the USB ports worked fine. In Device Manager,
the adpaters show up as being installed and working properly.

I am at my wit's end.

My DV camera worked fine on my now obsolete and cannibalized W2K system with
a dedicated DV capture card (Canopus).

I followed your link above to the RAM Electronics site, but the links to
which you referred are now invalid. Besides, the 1394 info discussed on that
site seemed to relate to Win98.

Any suggestions on how to proceed would be much appreciated.

I have a DVD burner and my digital video camera hooked up
to 1394 jacks. Now the computer won't recognize the video
camera. I have Service Pack 2 loaded, which I thought had
some fixes for that problem but it's not working. I've
tried deleting and reinstalling drivers but no luck.
Anyone run into this problem or know of a solution.
