Comparing USB to Ethernet is difficult. Any USB-device is talking USB1.1 at startup. So negotiation basically is transferring a data packet with the capabilities at a pre-defined data rate. While Ethernet has to negotiate the number of wires, full-duplex vs half-duplex (which depends on the number of wires). The code like Manchester vs. 4B5B. The main difference is, in USB the host decides on what to talk. In Ethernet there is no such instance. |
