   A four-port "long cable" "external box" USB hub A four-port "compact design" USB hub: upstream and downstream ports shown. A USB hub is a device that expands a single Universal Serial Bus (USB) port into several so that there are more ports available to connect devices to a host system, similar to a power strip. All devices connected through a ...

7. Compound device - Wikipedia

   en.wikipedia.org/wiki/Compound_device

   A USB compound device contains an embedded USB hub and one or more non-removable USB devices. [1] It may or may not have exposed downstream ports. The internal USB hub may be a physical IC that connects to other ICs, or the hub and all functions may be implemented in software on a single IC (though it is more common to integrate them as a composite device in this case).
