Can I connect USB 3.0 to USB 3.1?

The highest number always supports lower numbers, so USB 3.1 supports USB 2.1, USB 2.0, USB 1.1 and USB 1.0. The backward compatibility is because there is a mechanism to detect the protocol based on the impedance (and in USB2 also chirp which is not impedance based). USB is a one master, multiple slave protocol.


A host (master) assumes the highest protocol version it supports. when you connect a device (slave), it will connect to the highest version, and then go down to the lowest version of the protocol until it matches (if no, device not recognized will pop up). If your host is 3.0 then the maximum protocol version you will be able to connect to is 3.0 even if your device is 3.1 capable.


Next to a host and device, there are a kind of switches that are called hubs. They have one upstream (host side) connection and a number of downstream ports where you can connect a device or another hub. If your hub is 2.0, your host is 3.0 and your device is 3.1, the connection will be 2.0. The connection between host and device is decided by the highest common version in the connection. It includes hubs as well.
