Extensible Host Controller Interface (xHCI)

Extensible Host Controller Interface (xHCI) is an interface specification that defines Host Controller for a universal Serial Bus (USB 3.2), which is capable of interfacing with USB 1.x, 2.0, and 3.x compatible devices.

In case that a device (example, USB 3.2 Flash Drive) was connected to the computer, the computer will work as Host and the xHCI will be activated inside the processor.

The xHCI controller support link rate of up to USB 3.2 Gen 2x2 (20G).
