Funny enough I got shocked by a USB port once because it was “grounded”. I have my PC plugged into a fairly beefy power strip, and after getting zapped I figured out that the outlet the power strip plugged into was not grounded. So the power strip acted as a mediocre transformer, putting about 70v through the ground wire my PC was plugged into, then the grounded metal of the USB port.
Surprisingly didn’t fry anything in my PC, even that USB port still works just fine. Went through and checked all my outlets were properly grounded after that, thankfully it was just the one I needed to fix.
