I'm not familiar with USB specifically, but it's usually true that multi-core 
systems will have higher throughput than single core system. This is 
particularly true when dealing with slow I/O. And I believe that I have read 
somewhere than UHCI shifts the load of USB processing onto software, not the 
chipset. So, it's quite possible that a single core system will be slower, if 
there are any blocking I/O processes.

Cheers.
