The Standard OpenHCI USB Host Controller is a type of USB controller used in computers that support the Open Host Controller Interface (OpenHCI) standard. This standard was primarily designed for USB 1.1 devices, and the controller is responsible for managing USB devices connected to the system (such as keyboards, mice, printers, and storage devices).

While this standard was prevalent during the early days of USB (particularly for USB 1.0 and 1.1), it has been largely replaced by newer versions such as EHCI (Enhanced Host Controller Interface) for USB 2.0 and xHCI (Extensible Host Controller Interface) for USB 3.0 and later. However, the Standard OpenHCI USB Host Controller driver may still be relevant for older systems or legacy hardware.
