The USB implementation in itself didn't change (yet) in the Pro. The same DUET boards are fitted so any differences must come from secondary changes like changes on the mainboard PCB routing or improved AC isolation/decoupling. Another possibility is that you have a DUET board now that has slightly better components, clocks for example do each show different performance numbers if you'd measure and compare them (within a certain spec range/bandwidth of course).
