providing a root port router for a root port of a USB hub;
providing a data port router for each IO port of the USB hub;
routing data of a data stream serially between the root port router and each data port router without altering a frequency of the data stream;
routing data downstream from the root port though the root port router and through each of the data port routers to at least one IO port; and wherein routing data further comprises routing data upstream from one IO port though each data port router and through the root port router to the root port, wherein each data port router and the root port router delays the data stream by one bit during the routing.
12. The method of claim 11 wherein the frequency of the data stream further comprises 480 MHz.
13. The method of claim 11 further comprising providing a data control block for the data port router and each IO port to control enabling of each IO port during the routing.
