Abstract
A super-speed USB3.0 hub is described to which, after configuration, there are more high-speed devices than super-speed devices connected. The difference in the numbers is recognized and logic is provided that responds to an upstream host that there is an equal or balanced number of super-speed and high-speed ports active. This is accomplished by providing a number of “dummy” ports that make up any actual difference. The “dummy” ports are never active and are never connected to any device.
