USB2 has higher latencies, true, but if you are OK with them, then the USB2 interface is as capable of real-time communication as any other interface. There have been attempts to mitigate these latencies with various results. (Search research papers online.) USB3 should be much better in this regard. Cern. > > On Thu 18.
