While tampering with an Atmega, I had an accident with the wires hanging around, and I shorted the USB port on my computer.(The Atmega was connected to the computer via a USB-serial converter.) As a result, the computer no longer works. I can switch it on, and the power on LED comes to life, but then nothing happens, it does not reach the boot section. Which one is the most likely component to have died? The motherboard? Is it possible that I can fix the computer by replacing the motherboard?
By the way, isn't the USB port supposed to have a current limiter? At least, in the specifications, there are two current values, 100 mA, and 500 mA, and as far as I know, the USB port should be prepared for these contingencies, and be able to shut the port, if something happens there.
