Are USB4.0 and 3.0 compatible?
Yes, USB4.0 and 3.0 are compatible. USB4.0 is backward compatible and supports USB3.0 devices. USB4.0 devices can be plugged into 3.0 ports, but the transfer speed is 3.0. Of course, USB3.0 devices can be plugged into 4.0 ports, but the transfer speed is still 3.0. Only when the device that reaches USB4.0 is plugged into the 4.0 interface, in this case, the transmission speed is the propagation speed of usb4.0.
Also, USB 3.0 ports are usually blue, and USB 2.0 ports are red. Such a rule exists in the color of the interface on the computer and on the mobile hard disk.
