Generally computer busses are designed to operate without impact from external interference, bc there is so much of it around us all the time. You might be able to tip the scales though in some sensitive areas. Microphone input would be one, by influencing any high-impedance parts. Radio systems might be vulnerable... although typically they're designed so you don't get access to the baseband signal. For the most part, you'd be limited to up/down state. Coupling noise onto a USB cable though would require lots and lots power. I wonder if DRAM could be influenced? Hmmm....
