Macbook Pro USB Short-Circuit Protection

Hi,

Do Macbooks come with short-circuit protection on USB Ports? I have used many other laptop computers which all of them don't gave much problems if you short-circuit the USB ports. For Desktop PCs its no sweat. USB Controllers just shutdown to prevent damage.

I have a Arduino board and I do development on it. I closed my Macbook's lid so it went to sleep. Then I connected the Arduino board via USB and the opened my lid back and my Mac did not wake-up. From right that moment it was dead. I tried everything possible to start it again but it wont just power ON. When I connected the charger and tried to power ON it made some clicking noise three times but remained dead otherwise. Fortunately it was under warranty and I got it fixed. The repair guy said he had to replace the logic board. I understand its the equivalent of motherboards to other systems.

From that incident on wards I never connected and doubtful USB device or any Arduino and development board to my Macbook. Now I am scared to take that risk. If I do and it happens again Apple will make me sell my kidney just to replace its motherboard.

I have never had such a problems with other computers. All of the handle USB short circuits like "bring it on" and I am amazed to see 300$ laptop PCs can handle short circuit but with maximum damage of USB Ports not working only after making them suffer and torture with so many long duration short circuits, and here 2000$ device so heavily engineered die like a little girl while it just got punched with a feather.

Now I wanna do dev on arduino using my mac. I did all testing on the arduino board and it draws very less current through USB supply. So I ask again, do these delicate Macbooks have a protection circuit and should I try taking the risk of connection a dev board.
