Upstream USB connectors supply power at a nominal 5 V DC via the V_BUS pin to downstream USB devices. A stream pipe is a uni-directional pipe connected to a uni-directional endpoint that transfers data using an isochronous, [54] interrupt, or bulk transfer: The USB3.1 specification introduced an Enhanced SuperSpeed System – while preserving the SuperSpeed architecture and protocol ( SuperSpeed USB) – with an additional SuperSpeedPlus architecture and protocol (aka SuperSpeedPlus USB) adding a new coding schema (128b/132b symbols, 10 Gbps; also known as Gen 2), for some time period marketed as SupeerSpeed+ ( SS+).

USB device communication is based on pipes (logical channels). A pipe is a connection from the host controller to a logical entity within a device, called an endpoint. Because pipes correspond to endpoints, the terms are sometimes used interchangeably. Each USB device can have up to 32 endpoints (16 in and 16 out), though it is rare to have so many. Endpoints are defined and numbered by the device during initialization (the period after physical connection called "enumeration") and so are relatively permanent, whereas pipes may be opened and closed.Low-speed (LS) and Full-speed (FS) modes use a single data wire pair, labeled D+ and D−, in half-duplex. Transmitted signal levels are 0.0–0.3 V for logical low, and 2.8–3.6 V for logical high level. The signal lines are not terminated.

USB ports and connectors are often color-coded to distinguish their different functions and USB versions. These colors are not part of the USB specification and can vary between manufacturers; for example, the USB3.0 specification mandates appropriate color-coding while it only recommends blue inserts for Standard-A USB3.0 connectors and plugs.

The Micro-AB receptacle is capable of accepting Micro-A and Micro-B plugs, attached to any of the legal cables and adapters as defined in revision 1.01 of the Micro-USB specification. Micro-USB was embraced as the "Universal Charging Solution" by the International Telecommunication Union (ITU) in October 2009. [18] Full-featured USB-C 3.1 cables are electronically marked cables that contain a full set of wires and a chip with an ID function based on the configuration data channel and vendor-defined messages (VDMs) from the USB Power Delivery 2.0 specification. USB-C devices also support power currents of 1.5A and 3.0A over the 5V power bus in addition to baseline 900mA; devices can either negotiate increased USB current through the configuration line or they can support the full Power Delivery specification using both BMC-coded configuration line and legacy BFSK-coded V BUS line.

Shown with a centimeter ruler. Neither USB 1.0 nor 1.1 specified a design for any connector smaller than the standard type A or type B. Though many designs for a miniaturized type B connector appeared on many peripherals, conformity to the USB1. x standard was hampered by treating peripherals that had miniature connectors as though they had a tethered connection (that is: no plug or receptacle at the peripheral end). There was no known miniature type A connector until USB2.0 (revision 1.01) introduced one. a b c "Universal Serial Bus Micro-USB Cables and Connectors Specification" (PDF). USB Implementers Forum.

The operation modes USB3.2Gen2×2 and USB4Gen2×2 – or: USB3.2Gen2×1 and USB4Gen2×1 – are not interchangeable or compatible; all participating controllers must operate with the same mode. Because use of the USB logo is only permitted after compliance testing, the user can have confidence that a USB device will work as expected without extensive interaction with settings and configuration.

The connectors the USB committee specifies support a number of USB's underlying goals, and reflect lessons learned from the many connectors the computer industry has used. The connector mounted on the host or device is called the receptacle, and the connector attached to the cable is called the plug. [1] The official USB specification documents also periodically define the term male to represent the plug, and female to represent the receptacle, though these uses are inconsistent with established definitions of connector gender. [2] Portable devices having a USB On-The-Go port may want to charge and access a USB peripheral simultaneously, yet having only a single port (both due to On-The-Go and space requirement) prevents this. Accessory charging adapters (ACA) are devices that provide portable charging power to an On-The-Go connection between host and peripheral.Connector properties [ edit ] Non-standard "USB extension cable", plug on the left, receptacle on the right.

Many USB bridge / data transfer cables are still USB 2.0, but there are also a number of USB 3.0 transfer cables. Despite USB 3.0 being 10 times faster than USB 2.0, USB 3.0 transfer cables are only 2 - 3 times faster given their design. [ clarification needed] USB 3.0 also introduced the USB Attached SCSI protocol (UASP), which provides generally faster transfer speeds than the BOT (Bulk-Only-Transfer) protocol. a b c "10 Power Rules", Universal Serial Bus Power Delivery Specification revision3.1, version1.0, USB Implementers Forum , retrieved September 5, 2017
