> that had a separate controller/bus for their gigabit ethernet and USB 3 controllers Are you sure? As far as I could tell, they had a single USB 3 controller that had a 2 port hub. One port was connected to gigabit ethernet, while the other was connected to another two port hub which is the two ports on the device. ie all devices connected to USB 3 and the gigabit are sharing the controller and bandwidth. The background is the Exynos chip used was intended for the cell phone market, where there is no need for multiple USB 3 controllers, in addition the existing USB 2 controllers.
