JVC GR-D250 not recognize using firewire windows...

[prayami]

Hi,
I just got new PC with Vista. My JVC GR-D250 digital video camera was working with windows xp using USB. But
might be that laptop was slow or due to USB, it was very poor quality.
Now I tried to connect in this new PC with Vista using firewire but nothing happen on pc side.
How can I know, what is the problem?
Is it require to install any driver for vista? If yes where can i get it? I bought the display piece and don't have any CD for this camera. Microsoft Movie Maker is already installed in my new PC.
What should happen when i connect the firewire and turn on the camera. I assume it will be same like usb...new hardware found etc. Or driver not recognize etc.

But in my case it is not giving me any messages. Just Nothing Happen ??
I have checked in Device Manager but it seems like nothing happen.

plz guide me, thanks,

I figured out the problem.
On JVC website it is written that, this camera may not function properly with some of the vista PC using firewire.

I observe that, with my Desktop PC having 6pin firewire and vista, it is not working.
But with my laptop having vista with 4-pin firewire, it is working fine.

This problem may be fixed in the SP1 of the vista.

Thanks,
