2. Data interface, 3.0 is full-duplex, four-way differential signals independent of USB 2.0 signals, supporting simultaneous bidirectional data transmission
2.0 is half-duplex, two-way differential signals, one-way data transmission, and the transmission direction of the main line needs to be negotiated in advance.
3. Number of signal lines, 3.0 is 4 SuperSpeed data lines, 2 HighSpeed data lines and 2 power and ground lines
2.0 is a 2-way LS/ FS/ HS data cable, 2 power and ground wires
4. bus transaction Protocol, 3.0 is a host-led asynchronous transmission flow control , packet transmission can be explicitly routed
2.0 is a host-led polling mode of transmission flow control, and packet transmission is broadcast to all devices.
5. Power management, 3.0 has many other link power management, supporting Idle, sleep and suspend states
2.0 is managed on the port, which can be entered in the entry/ There are two other hang-up states on exit
6. Bus power, 3.0 is similar to USB 2.0, except that the unconfigured power supply has 50% increment, the configured power supply has 80% increase in
7. Host controller, 3.0 uses xHCI, and 2.0 uses EHCI. xHCI provides virtualization technology support.
