Enhanced Host Controller Interface Specification
WEBEnhanced Host Controller Interface Specification. The Enhanced Host Controller Interface (EHCI) specification describes the register-level interface for a host controller for the Universal Serial Bus (USB) Revision 2.0. The specification includes a description of the hardware and software interface between system software and the host ...
Host controller interface (USB, Firewire) - Wikipedia
WEBExtensible Host Controller Interface. Extensible Host Controller Interface ( xHCI) is the newest host controller standard that improves speed, power efficiency and virtualization over its predecessors. The goal was also to define a USB host controller to replace UHCI/OHCI/EHCI.
Enhanced Host Controller Interface for USB 2.0: Specification
WEBThe document describes the enhanced host controller interface for universal serial bus revision 2.0, including the interface between system software and host controller hardware interface. • Full support for all USB 2.0 features. • Low-risk support for full- and low-speed peripherals. • System power management.

EHCI driver — The Linux Kernel documentation
WEBDec 27, 2002 · The EHCI driver is used to talk to high speed USB 2.0 devices using USB 2.0-capable host controller hardware. The USB 2.0 standard is compatible with the USB 1.1 standard. It defines three transfer speeds: “High Speed” 480 Mbit/sec (60 MByte/sec) “Full Speed” 12 Mbit/sec (1.5 MByte/sec) “Low Speed” 1.5 Mbit/sec.
WEBExtended Host Controller Interface (EHCI): Created for USB 2.0 after USB-IF requested that a single host controller specification be created. EHCI is used for High-Speed transactions and delegates Low-Speed and Full-Speed transactions to an OHCI or UHCI sister controller.
WEBThe EHCI specification defines a register set and data structures that control USB data movement. The EHCI specification was designed for the PC world and therefore allows for an extremely robust host implementation supporting many different types of devices on a …

WEBApr 20, 2021 · The Enhanced Host Controller Interface (EHCI) is the single method of interfacing with USB 2.0. This makes life a lot easier than with USB 1.0, where two incompatible standards ( OHCI and UHCI) both survived. This is because the USB-IF insisted on a single implementation, produced by Intel.
Extensible Host Controller Interface - Wikipedia
WEBThe OHCI and UHCI controllers support only USB 1 speed devices (1.5 Mbit/s and 12 Mbit/s), and the EHCI only supports USB 2 devices (480 Mbit/s). The xHCI architecture was designed to support all USB speeds, including SuperSpeed (5 Gbit/s) and future speeds, under a single driver stack.
