Short answer no, long answer not in this scenario.
You need to know the circuitry of the light and have the USB connected to a controller that is able to turn the light on (which almost no lamps in the world have). Then you need to write the low-level (which VB is not) assembler that tells the controller and the computer how to exchange data through the USB port.

you might want to try using something other than visual basic. it might be easier.

If really want to do it in VB you could make first a dll in assembly or search the net for such lybraries, I don't know if somebody built a thing like this...
