USB 3.0在这两年进展快速,许多主板以及笔记本电脑纷纷导入USB 3.0接口,而USB IF今年也在Computex南港展区设立摊位,倡导USB 3.0、也就是SuperSpeed USB的认证重要。今天就由USB IF的主席Jeff Ravencraft亲自聊聊USB 3.0的进展。

USB 3.0 is gaining quite a bit of popularity in the past two years, and now we can find this handy port on lots of laptops and motherboards. We visited the USB IF booth at Computex this year and had a chat with the president of USB IF, Jeff Ravencraft on the future of USB 3.0.

More on the interview after the break.

Jeff提到,USB是PC史上最成功的通用接口,由于即插即用,并且同时可以满足数据与供电,深受消费者的喜好。USB IF的身份像是个贸易协会,协助组织成员以及非成员、但希望采用USB接口的厂商进行验证与技术推广,并且拥有严谨而开放的测试过程以及相关安全性规范。USB IF也会捍卫认证标签的使用权,避免未通过认证的公司擅自使用或是仿制相似的商标贴在劣质产品混淆市场,并因此伤害通过USB IF的认证产品。

现在已经有超过100亿的USB装置在世面上流通,而且近年开始,每年少说有近30亿个采用USB接口的装置与终端被生产;此外在USB IF与欧盟合力推动下,未来销往欧盟会员国的手机都需要采用micro USB接口充电,除了简化充电接口,并可同时满足数据传输之用,并且预估每年至少减少五万顿的充电器设备废弃物。

USB 3.0承袭USB的优点,并且具备向下兼容性,供电也较以往提升一倍,达到2A,使得充电速度加速一倍,但由于电源管理更为进化,可降低接口整体1/3的功耗;并且可以带来近10倍的传输速度,是相当成熟且可用的接口标准。去年瑞萨(前NEC半导体部门)出货近两千万个USB 3.0控制器芯片,而在去年底通过认证的Fresco Logic也在2010年底前达到一百万颗控制器的出货。

Jeff told us that USB is by far the most successful universal plug in computing. USB IF is more like a professional organization. They help both members and non-members but wish to facilitate strict licensing and rigorous testing of USB products. They are also strict on the use of the certification label.

Apparently there are more than 10 billion USB devices on the market right now with 3 billion new yearly. More importantly, in the near future, all cell phones in the EU will need to have a micro USB port for charging to significantly reduce the waste generated from unwanted chargers.


2011年USB需求更快速增加,华硕光是Q1就已经出货两百万张搭载USB 3.0的主板(包括笔电),技嘉更预估在今年底前,会有750万张以上搭载USB 3.0的主板出货。除了AMD已经通过USB IF认证外,Intel也允诺2012年春季的Ivy Bridge平台将会纳入USB 3.0。

而USB 3.0未来除持续进行产品认证动作以外,Jeff也透露USB 3.0接下来会沿用现有的接口形式,但将传输速度提升到25Gb以上,持续提供基于低成本、高带宽的通用接口技术。

至今已经有236项USB 3.0装置通过USB IF的认证,并且在今年宣布加入祥硕与钰创两家台湾厂商,以及AMD将USB 3.0整合至芯片组后,目前已经有六家控制相关厂商通过USB IF认证。Jeff强调,USB是一项开放的通用标准技术,任何厂商都可以在网络直接下载技术白皮书,除了USB IF成员可将产品送至全球六个Work Shop(其中台北站每六周举办一次。)直接进行兼容验证外,非成员终端产品都可送至各个通过认证的第三方实验室进行验证。

应该会有不少人会想向Jeff询问关于Intel Thunderbolt接口对于USB 3.0的影响,Jeff则表示,他无法对于Intel的技术多加评论,但是他认为,USB 3.0是一项已经低成本、普及且开放的标准,并且USB IF积极推动完整的测试程序,使市面上通过认证的USB产品都能够确保兼容性、可靠性以及安全性,并且USB接口已经深入多数用户的生活,这是USB接口最大的竞争优势。

USB 3.0 is much faster than the previous gen and is backward compatible. In 2011, there are more demands, as ASUS along has passed 2 million USB 3.0-equipped motherboards (including laptops), and Gigabyte will have more than 7.5 million motherboards coming out of the production line by the end of the year. So far AMD has been approved by USB IF, and Intel has promised to integrate USB 3.0 in their new Ivy Bridge due in spring 2012.

Jeff said that he cannot comment on Intel's Thunderbolt but he has faith that USB 3.0 will continue to populate the tech industry.
