Forgive me if I don't understand what the REGEN does, but as far as I do understand, differences in the USB ports may not matter as the REGEN takes the USB signal, does some kind or other type of processing and then regenerates a brand new, cleaned up signal of its own making to the dac. So, if my understanding is correct, the origins of the original USB signal should be irrelevant (???)
