In July 2012, the USB Promoters Group announced the finalization of the USB Power Delivery (USB-PD) specification (USB PD rev. 1), an extension that specifies using certified PD aware USB cables with standard USB Type-A and Type-B connectors to deliver increased power (more than 7.5 W maximum allowed by the previous USB Battery Charging ...
The USB 3.0 specification defined a new architecture and protocol named SuperSpeed (aka SuperSpeed USB, marketed as SS), which included a new lane for a new signal coding scheme (8b/10b symbols, 5 Gbit/s; later also known as Gen 1) providing full-duplex data transfers that physically required five additional wires and pins, while preserving the ...
A deprecated [2] SuperSpeed+ USB 10 Gbit/s packaging logo. In January 2013 the USB group announced plans to update USB 3.0 to 10 Gbit/s (1250 MB/s). [60] The group ended up creating a new USB specification, USB 3.1, which was released on 31 July 2013, [61] replacing the USB 3.0 standard.
The written USB 3.0 specification was released by Intel and its partners in August 2008. The first USB 3.0 controller chips were sampled by NEC in May 2009, [4] and the first products using the USB 3.0 specification arrived in January 2010. [5] USB 3.0 connectors are generally backward compatible, but include new wiring and full-duplex operation.
The Type-C specification does not name specific DP speeds that it considers supported for passive cables where support is optional for active cables. The USB-C presentation on DP Alt mode [47] calls out passive full-featured USB-C cables for their DisplayPort support and headroom for future DP speed increases. HBR3 was the highest available DP ...
Power equals voltage times current. A USB port that draws 500 mA (0.5 A) at 5 volts is drawing 2.5 watts of power. In Bus-powered USB hubs, each USB port can supply power as well as transfer data. A self-powered hub takes its power from an external power supply unit and can therefore provide full power (up to 500 mA) to every port. Self-powered ...
In computing, the USB human interface device class (USB HID class) is a part of the USB specification for computer peripherals: it specifies a device class (a type of computer hardware) for human interface devices such as keyboards, mice, touchscreen, game controllers and alphanumeric display devices.
USB-C plug USB-C (SuperSpeed USB 5Gbps) receptacle on an MSI laptop. USB-C, or USB Type-C, is a 24-pin, reversible connector (not a protocol) that supersedes previous USB connectors and can carry audio, video, and other data, to connect to monitors, external drives, hubs/docking stations, mobile phones, and many more peripheral devices.
