Applications
USB 3.0/USB 3.1 Gen 1 opens up the laneways and provides more headroom for devices to deliver a better overall experience. Where USB
video was barely tolerable previously (both from a maximum resolution, latency, and video compression perspective), it's easy to imagine
that with 5-10 times the bandwidth available, USB video solutions should work that much better. Single-link DVI requires almost 2Gbps
throughput. Where 480Mbps was limiting, 5Gbps is more than promising. With its promised 4.8Gbps speed, the standard will find its way
into some products that previously weren't USB territory, like external RAID storage systems.
Listed below are some of the available SuperSpeed USB 3.0/USB 3.1 Gen 1 products:
• External Desktop USB 3.0/USB 3.1 Gen 1 Hard Drives
• Portable USB 3.0/USB 3.1 Gen 1 Hard Drives
• USB 3.0/USB 3.1 Gen 1 Drive Docks & Adapters
• USB 3.0/USB 3.1 Gen 1 Flash Drives & Readers
• USB 3.0/USB 3.1 Gen 1 Solid-state Drives
• USB 3.0/USB 3.1 Gen 1 RAIDs
• Optical Media Drives
• Multimedia Devices
• Networking
• USB 3.0/USB 3.1 Gen 1 Adapter Cards & Hubs
Compatibility
The good news is that USB 3.0/USB 3.1 Gen 1 has been carefully planned from the start to peacefully co-exist with USB 2.0. First of all,
while USB 3.0/USB 3.1 Gen 1 specifies new physical connections and thus new cables to take advantage of the higher speed capability of
the new protocol, the connector itself remains the same rectangular shape with the four USB 2.0 contacts in the exact same location as
before. Five new connections to carry receive and transmitted data independently are present on USB 3.0/USB 3.1 Gen 1 cables and only
come into contact when connected to a proper SuperSpeed USB connection.
Windows 10 will be bringing native support for USB 3.1 Gen 1 controllers. This is in contrast to previous versions of Windows, which
continue to require separate drivers for USB 3.0/USB 3.1 Gen 1 controllers.
USB Type-C
USB Type-C 是全新的小型物理连接器。该连接器本身可支持各种新的 USB 标准，如 USB 3.1 和 USB Power Delivery (USB PD)。
替代模式
USB Type-C 是新的小型连接器标准。它大约是旧的 USB Type-A 插头的三分之一。这是单一连接器标准，每个设备都应能够使用。
USB Type-C 端口使用“备选模式”支持各种不同的协议，允许您的适配器从一个 USB 端口输出 HDMI、VGA、DisplayPort 或其他连接
类型
USB Power Delivery
USB PD 规格还与 USB Type-C 密切相关。当前，智能手机、平板电脑和其他移动设备通常使用 USB 连接进行充电。USB 2.0 连接可
以提供最高 2.5 W 电源 — 这仅仅可以为您的手机充电。例如，笔记本电脑可能需要最高 60 W。USB Power Delivery 规格将此电源交
付能力提升到最高 100 W。它是双向的，设备可以发送或接收电力。并且此电力在设备跨连接传输数据的同时进行传输。
这预示着可以抛却一切专属笔记本电脑充电缆线，只通过标准 USB 连接即可为任何设备充电。从今天开始，您可以使用为智能手机
和其他便携式设备充电的便携式电池包为您的笔记本电脑充电。您可以将笔记本电脑插入连接到电源缆线的外部显示屏，该外部显
示屏将为您的笔记本电脑充电 — 只需通过一个小型 USB Type-C 接口。要使用此方法，设备和缆线必须支持 USB 供电。仅仅具有
USB Type-C 接口并不意味着它们可以执行这些操作。
USB Type-C 和 USB 3.1
USB 3.1 是新的 USB 标准。USB 3 的理论带宽是 5 Gbps，而 USB 3.1 是 10 Gbps。带宽倍增，速度堪比第一代 Thunderbolt 连接器。
USB Type-C 与 USB 3.1 不同。USB Type-C 仅仅是接口类型，其基础即使可能仅仅是 USB 2 或 USB 3.0。实际上，Nokia 的 N1
Android 平板电脑使用 USB Type-C 连接器，但其基础技术是 USB 2.0 — 甚至不是 USB 3.0。不过，这些技术紧密相关。
