4 Pin FireWire to USB cable

Hi
I got a firewire cable recently, (4 pin to usb) and my computer doesnt seem to read the device while plugged in. Do I need to install any driver for this.My OS is Windows XP(With sp2)

Hi
I am sure about the pin configuration.
I am able to plug the 4-pin fireWire to my Camcoder and USB to computer.

Its a DV Cable. It plugs into the DV port on your camcorder and the firewire port on your computer To read from it you will need software, like PowerDirector.

I __really___ wish all the hardware gurus would take a step back and consider that people *might* know what they are talking about.

In short...

"Firewire and USB are not the same technology and don't use the same communication signals. So, no matter how you wire it, the two just won't communicate."

[Bzzz] Wrong answer.

Apparently, how you 'wire' it does matter. Otherwise, Pixela wouldn't be making $120 a cable for these:

Now, dhinesh's link is broken, and I'm too lazy to look into it, so I'll admit that perhaps the link points to a true firewire-firewire or usb-usb cable. But, what if.. what if dhinesh bought one of these Pixela cables and came here looking for help?

Firewire and USB don't have to communicate - they can use a converter cable...

To be lenient, I've been looking for something like this cable for years, and it is the only one I've seen - but before being so adamant that something can't be done, double check.

What driver do you need, I bought one of these cables and am running Windows Vista?
