The newest available version of this specification is USB 2.0 Rev. 2.0. [17] USB 2.0 abilities uses separate wires on the Type-C connector that are not used by USB 3.2 or USB4 connections. USB4, just as USB 3.2 before provides a parallel USB 2.0 connection to be present on the same cable to support backwards compatibility to USB 2.0 modes.
USB-C Thunderbolt 3, 4, or 5 connector. Thunderbolt 3 is a hardware interface developed by Intel. [ 74] It shares USB-C connectors with USB, supports USB 3.1 Gen 2, [ 75][ 76][ 77] and can require special "active" cables for maximum performance for cable lengths over 0.5 meters (1.5 feet).
Apple Lightning to USB-A cable. Lightning is an 8-pin digital connector. Unlike the 30-pin dock connector it replaced (and USB Type-A and -B connectors), it is reversible. [20] Most Lightning devices only supported USB 2.0, which has a maximum transfer speed of 480 Mbit/s or 60 MB/s. With USB 2.0, only one lane is in use at a time.
The Linux kernel has supported USB mass-storage devices since its 2.4 series (2001), and a backport to kernel 2.2.18 [2] has been made. In Linux, more features exist in addition to the generic drivers for USB mass-storage device class devices, including quirks, bug fixes and additional functionality for devices and controllers (vendor-enabled functions such as ATA command pass-through for ATA ...
The eXtensible Host Controller Interface ( xHCI) is a technical specification that provides a detailed framework for the functioning of a computer's host controller for Universal Serial Bus (USB). Known alternately as the USB 3.0 host controller specification, xHCI is designed to be backward compatible, supporting a wide range of USB devices ...
The USB 3.0 Micro-B plug effectively consists of a standard USB 2.0 Micro-B cable plug, with an additional 5 pins plug "stacked" to the side of it. In this way, cables with smaller 5 pin USB 2.0 Micro-B plugs can be plugged into devices with 10 contact USB 3.0 Micro-B receptacles and achieve backward compatibility.
The USB Implementers Forum ( USB-IF) is a nonprofit organization created to promote and maintain USB (Universal Serial Bus), a set of specifications and transmission procedures for a type of cable connection that has since become used widely for electronic equipment. Its main activities are currently the promotion and marketing of USB, Wireless ...
USB ports and cables are used to connect hardware such as printers, scanners, keyboards, mice, flash drives, external hard drives, joysticks, cameras, monitors, and more to computers of all kinds. USB also supports signaling rates from 1.5 Mbit/s (Low speed) to 80 Gbit/s (USB4 2.0) depending on the version of the standard.
