Больше 800Кб/сек не может быть теоретически. HUB не умеет перепаковывать full speed в high speed, поэтому вся система встанет в full speed с соответствующим ограничением суммарной скорости.
В спецификации есть:
When the hub upstream facing port is attached to an electrical environment that is operating at high-speed,
the full-/low-speed hub repeater is not operational. In this electrical environment when a high-speed device
is attached on downstream facing port, the routing logic will connect the port to the hub repeater and the
hub repeater must operate as a high-speed repeater. In this case, when a full-/low-speed device is attached
on a downstream facing port, the routing logic must connect the port to the transaction translator
Так вот, transaction translator - это как раз тот самый перепаковщик.
