I've fried a brand new board (disabling half the USB ports) in the process of plugging in a standard MicroUSB3 connector - must've accidentally shorted some pins somehow. Point is, it's still quite easy to damage. | |

| Dec 23, 2013 at 0:14 | comment | added | ThiefMaster | I think modern mainboards are somewhat tolerant. When tinkering around with an AVR I accidentally connected GND to VCC and besides the device being disconnected by the system (i.e. windows played the "device disconnected" sound) nothing happened at all. It might be worth noting that it was no direct usb connection. VCC came through the ISP cable (which got it from USB) and GND came through an USB=>serial cable. | |
