A method, device, system, and computer readable medium are disclosed. In one embodiment the method includes dynamically associating a newly active port in a computer system with a first host controller. The first association happens when a total number of currently active ports in the computer system is less than a maximum capacity number of ports for the first host controller. The method also includes dynamically associating the newly active port in the computer system with a second host controller. The second association happens when the total number of currently active ports in the computer system is greater than or equal to the maximum capacity number of ports for the first host controller. In this method, each port, the first host controller, and second host controller all utilize the same protocol.
