Here is a USB pinout. On my lights I have red and black cables, black almost always means ground. So you would just solder the red wire to pin 1 and the black wire to pin 4 on a male USB plug.

USB can only provide 5v as opposed to the 12v CCFLs usually uses so it won't be as bright.

thanx! that helps
now, is there anyway that i can get more power through the usb cable?

also i was wondering if those usb cables that most external hard drives use [ the 2 male to 1 mini usb cable] could change that

There is no way to get more power through USB.

 

External hard drives are also not powered by USB, they are connected to a wall outlet. You could always make/buy a small psu to convert AC into DC 12v if you want, but it won't require USB.

 

I have never opened a PS3 before but if you feel daring you could try and find a 12v power source and mod it to work with your CCFL.
