Connectors [ edit ] Comparison of legacy USB connector plugs, omitting the current standard Type-C plugs 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. a b c "10 Power Rules", Universal Serial Bus Power Delivery Specification revision3.1, version1.0, USB Implementers Forum , retrieved September 5, 2017 What Is the USB 3.0 Cable Difference".

The 24-pin double-sided connector provides four power–ground pairs, two differential pairs for USB2.0 data (though only one pair is implemented in a USB-C cable), four pairs for SuperSpeed data bus (only two pairs are used in USB 3.1 mode), two "sideband use" pins, V CONN +5V power for active cables, and a configuration pin for cable orientation detection and dedicated biphase mark code (BMC) configuration data channel. [27] [28] Type-A and Type-B adaptors and cables are required for older hosts and devices to plug into USB-C hosts and devices. Adapters and cables with a USB-C receptacle are not allowed. [29]

They are commonly found on rechargeable technologies and smaller peripherals. Micro-USB B, being the smaller of the two, is often seen on newer devices, while the slightly bigger USB Mini-b is now less widely used. Micro-USB was endorsed as the standard connector for data and power on mobile devices by the cellular phone carrier group Open Mobile Terminal Platform (OMTP) in 2007. [17] 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. Unlike Type-A and Type-B connectors, female USB-C ports can accept a male USB-C plug inserted either way up, as the terminals at both port and plug are completely symmetrical. Type-C USB connectors can be used with adapters that allow the connection of various other USB types, and they are capable of transferring power and data to/from all previous generations of USB devices.Apple's Lightning to Micro-USB adapter now available in US, not just Europe anymore", Engadget, 3 November 2012, archived from the original on 26 June 2017

Before the Battery Charging Specification was defined, there was no standardized way for the portable device to inquire how much current was available. For example, Apple's iPod and iPhone chargers indicate the available current by voltages on the D− and D+ lines. When D+ = D− = 2.0V, the device may pull up to 900mA. When D+ = 2.0V and D− = 2.8V, the device may pull up to 1A of current. [53] When D+ = 2.8V and D− = 2.0V, the device may pull up to 2A of current.

USB3.0 provides two additional differential pairs (four wires, SSTx+, SSTx−, SSRx+ and SSRx−), providing full-duplex data transfers at SuperSpeed, which makes it similar to Serial ATA or single-lane PCI Express. a b c "Universal Serial Bus Micro-USB Cables and Connectors Specification" (PDF).

It draws 1 unit load for the hub controller and 1 unit load for each of at most 4 ports. The hub may also have some non-removable functions in place of ports. A self-powered hub is a device that provides high-power ports by supplementing the power supply from the host with its own external supply. Optionally, the hub controller may draw power for its operation as a low-power device, but all high-power ports must draw from the hub's self-power.a b c d e "Universal Serial Bus Cables and Connectors Class Document Revision 2.0" (PDF).

[13] [16] The Micro connector is also designed to reduce the mechanical wear on the device; instead, the easier-to-replace cable is designed to bear the mechanical wear of connection and disconnection. The Universal Serial Bus Micro-USB Cables and Connectors Specification details the mechanical characteristics of Micro-A plugs, Micro-AB receptacles (which accept both Micro-A and Micro-B plugs), Double-Sided Micro USB, and Micro-B plugs and receptacles, [16] along with a Standard-A receptacle to a Micro-A plug adapter.
