AFAIK, it is only USB 3 that introduced proper use of CPU interrupts for signalling, while previous releases required constant polling by the OS. Combining that with the larger packet size, a USB 3 stack might actually end up going easier those low-performance chips.
At least if OSs and devices supported it well, which, considering how well Linux 3.2 can react on dmesg and elsewhere when I plug something into my USB 3 ports, is far from a given.
