It has largely replaced interfaces such as serial ports and parallel ports and has become commonplace on a wide range of devices. Examples of peripherals that are connected via USB include computer keyboards and mice, video cameras, printers, portable media players, mobile (portable) digital telephones, disk drives, and network adapters. A USB system consists of a host with one or more downstream facing ports (DFP), [52] and multiple peripherals, forming a tiered- star topology. Additional USB hubs may be included, allowing up to five tiers. A USB host may have multiple controllers, each with one or more ports. Up to 127 devices may be connected to a single host controller. [53] [30] :8–29 USB devices are linked in series through hubs. The hub built into the host controller is called the root hub. Watt to Know About iPhone & iPad Power Adapters | Analysis".

Retrieved 21 December 2014.There are several minimum allowable voltages defined at different locations within a chain of connectors, hubs, and cables between an upstream host (providing the power) and a downstream device (consuming the power). To allow for voltage drops, the voltage at the host port, hub port, and device are specified to be at least 4.75V, 4.4V, and 4.35V respectively by USB2.0 for low-power devices, [a] but must be at least 4.75V at all locations for high-power [b] devices (however, high-power devices are required to operate as a low-powered device so that they may be detected and enumerated if connected to a low-power upstream port). The USB3. x specifications require that all devices must operate down to 4.00V at the device port. USB bridge cables, or data transfer cables can be found within the market, offering direct PC to PC connections. A bridge cable is a special cable with a chip and active electronics in the middle of the cable. The chip in the middle of the cable acts as a peripheral to both computers and allows for peer-to-peer communication between the computers. The USB bridge cables are used to transfer files between two computers via their USB ports. For a host providing power to devices, USB has a concept of the unit load. Any device may draw power of one unit, and devices may request more power in these discrete steps. It is not required that the host provide requested power, and a device may not draw more power than negotiated.

Mini-USB: Mini-USB connectors were popular in the past but are now less common. They come in two forms: Mini-A and Mini-B. These cables were commonly used for connecting digital cameras, older smartphones, and other portable devices. USB2.0 provides for a maximum cable length of 5 meters (16ft 5in) for devices running at high speed (480Mbit/s). [88] The USB Power Delivery specification revision2.0 (USB PD Rev. 2.0) has been released as part of the USB3.1 suite. [56] [64] [65] It covers the USB-C cable and connector with a separate configuration channel, which now hosts a DC coupled low-frequency BMC-coded data channel that reduces the possibilities for RF interference. [66] Power Delivery protocols have been updated to facilitate USB-C features such as cable ID function, Alternate Mode negotiation, increased V BUS currents, and V CONN-powered accessories. Because of the previous confusing naming schemes, USB-IF decided to change it once again. As of 2 September 2022, marketing names follow the syntax "USB xGbps", where x is the speed of transfer in Gb/s.
