Can a firewire cable(4 pin, image: http://en.wikipedia.org/wiki/Image:FireWire_cables.jpg) charge a PSP? Because, im about to get a PSP from a good friend of mine, but wont include charger because he says he lost it. So instead of buying a charger for $15(cause i have better things to spend) can i charge the PSP with a 4 PIN FIREWIRE Cable? Just found it lying around, decided to use it. Can i also transfer files while im charging it? Like photos, music, etc. This is for a OLD PSP, meaning the fat PSP. And will a 4 pin fit? You can see a demonstration of the 4pin firewire cable on the link i posted.
