That is true. However there is a limit to how much abuse they can take  
if you hook the lines up someplace they shouldn't be. For example, if  
you send enough of an ESD through it, the USB port may become  
permanently damaged.

My point was that you're hooking your computer up to some experimental  
circuit...you may wind up damaging the computer that way. A better  
solution is to get an external power supply rigged up.
