Digital BW, The Print

I run my Epson 2450 from a powered Belkin hub. As all here agree,
it's a remarkable device with acceptable speeds even with Win98se and
USB1. However, I have a USB2 card awaiting me at a local shop; among 
its other virtues, the 2450 is USB2-ready. Question is, will the
increased speed carry through the hub to the scanner, or does USB2 
require ahub manufactured for it?
