I'm trying to interface USB 2.0 port with PIC18F2550. I am planning to supply circuit with the 5V voltage from USB port as well. I am worried about one matter, what happens if I accidentally short-circuit any two pins of USB port? Is there any internal protection for this possibility, or should I implement it explicitly?
 

New versions of PC's and laptops are provided with short circuit protection with poly fuses to prevent any short circuits in the USB port. Whenever a short occurs, a pop out window will notify bout the situation. But anyways, take possible precautions as prevention is better than cure. Cheers.
