USB3 - Yenra

USB 3.0 connector and cable
A highly detailed and realistic image of a USB 3.0 connector and cable. The USB 3.0 connector should be shown in close-up, with its distinct blue color that differentiates it from earlier versions. The cable should be slightly coiled, reflecting a practical use case. The background is a blurred office environment with a hint of a computer and other peripherals, emphasizing the everyday use of the connector in modern technology settings. The lighting should highlight the reflective metallic parts of the connector and the texture of the cable.

USB 3, also known as USB 3.1 Gen 1, offers several improvements over previous USB standards:

The major advantages of USB 3 over its predecessors are significantly faster data transfer speeds, increased power delivery, and full duplex data transmission while remaining backwards compatible.

On August 13, 2008, Intel announced the availability of the Extensible Host Controller Interface (xHCI) draft specification revision 0.9 in support of the USB 3.0 architecture, also known as SuperSpeed USB. The xHCI draft specification provides a standardized method for USB 3.0 host controllers to communicate with the USB 3.0 software stack. Interoperability among devices from multiple manufacturers is important for consumer adoption of SuperSpeed USB products. The Intel xHCI draft specification revision 0.9 supports compatibility among various implementations of USB devices and will make it easier to develop software support for the industry.

The specification describes the registers and data structures used to interface between system software and the hardware, and are developed to be compatible with the USB 3.0 specification being developed by the USB 3.0 Promoter Group. Intel plans to make available a revised xHCI 0.95 specification in the fourth quarter. The updated revision of the specification will also be released under RAND-Z licensing terms via an xHCI adopter's agreement.
