First up, note that if this was trivial to do it would be an attack vector. At one stage you could do this with USB storage and an autoplay that sent internet explorer off somewhere but would be somewhat alarmed if that was still possible on any sensibly configured system. There are some options that use USB keyboard code to type out the address, the polite way is to ask the user to open a browser of their choice and then press a device button to have it type address, the impolite way is to steal the mouse and keyboard and try various blind key/movements to get a browser open and address entered.
In general USB devices are not supposed to be able to cause arbitrary execution to happen on the host computer.
