Abstract

Aspects for high speed USB data routing are presented. The aspects include routing a data stream to and from USB I/O ports serially, and maintaining a frequency of the data stream during the routing. Additionally, a root port router is provided for the root port and a data port router is provided for each I/O port, wherein each data port router delays the data stream by one bit during the routing.
