... The upstream facing port can be connected to a Hi-Speed USB host or hub Original USB host or hub. If the upstream facing port is connected to a Hi-Speed USB host or hub, then the ISP1521 will operate as a Hi-Speed USB hub. That is, it will support high-speed, full-speed and low-speed devices connected to its downstream facing ports. If the upstream facing port is connected to an Original USB host or hub, then the ISP1521 will operate as an Original USB hub ...

... Hub repeater A hub repeater manages connectivity on a per packet basis. It implements packet signaling connectivity and resume connectivity. There are two repeaters in the ISP1521: a Hi-Speed USB repeater and an Original USB repeater. The only major difference between these two repeaters is the speed at which they operate. When the hub is connected to an Original USB system, it automatically switches itself to function as an Original USB hub ...
