USB thing? Answered

Is there a way to make a USB thing that lights up a led (<-- That's the easy part) and tells the computer that the USB port works?

If the USB port works, the computer already knows.

Without adding some chips to create data to the computer the only thing you could check would be that the power works. You need some sort of data and some programming to check the data lines.

Hey, do you think we could give him a schematic to a voltage multiplier, and tell him to hold onto the two output wires while he plugs it in?
