IR Sensor Bar for usb

[philc]

Hi, i want to convert my original wii sensor bar to usb or power adapter.
When try to cut the wires from sensor bar and put on a power adapter 5v the IR don't show, when i put in wii the IR turns on.

Someone have a diagram to do this?

I think i need a resistor to change some volts and make the IR turn on

5v isn't enough for the wii sensor bar (the wii gives it 12v).
