The USB Device Working Group has laid out specifications for audio streaming, and specific standards have been developed and implemented for audio class uses, such as microphones, speakers, headsets, telephones, musical instruments, etc.
It is reversible and can support various functionalities and protocols including USB; some are mandatory, many optional, depending on the type of the hardware: host, peripheral device, or hub. Its efficiency is dependent on a number of factors including physical symbol encoding and link level overhead. Low-power devices may draw at most 1 unit load, and all devices must act as low-power devices before they are configured.For example, Apple's iPod and iPhone chargers indicate the available current by voltages on the D− and D+ lines. For example, a USB device that the seller intends to be just a flash drive can "spoof" an input device like a keyboard. This means it is more often found on peripheral devices designed to connect directly to the host device, to send data to it. provides for a maximum cable length of 5 meters (16ft 5in) for devices running at high speed (480Mbit/s).
A device connected by eSATA appears as an ordinary SATA device, giving both full performance and full compatibility associated with internal drives. Small devices can be powered directly from the USB interface, eliminating the need for additional power supply cables. Examples include USB-powered keyboard lights, fans, mug coolers and heaters, battery chargers, miniature vacuum cleaners, and even miniature lava lamps.
inch HDD/SSD; on a desktop workstation it can additionally supply 12V to power larger devices including 3. USB can cause ground loop problems between equipment, because it connects ground references on both transceivers.
All current OTG devices are required to have one, and only one, USB connector: a Micro-AB receptacle. Several manufacturers offer external portable USB hard disk drives, or empty enclosures for disk drives. Apple, one of the original MoU signers, makes Micro-USB adapters available—as permitted in the Common EPS MoU—for its iPhones equipped with Apple's proprietary 30-pin dock connector or (later) Lightning connector. Isochronous transfers At some guaranteed data rate (for fixed-bandwidth streaming data) but with possible data loss (e.They are also capable of providing DisplayPort Alternate Mode as well as DisplayPort over USB4 Fabric, making the function of a Thunderbolt3 port a superset of that of a USB3. Low-power and high-power devices remain operational with this standard, but devices using SuperSpeed can take advantage of increased available current of between 150mA and 900mA, respectively.
Higher-speed development of the USB standard gave rise to another family of connectors to permit additional data paths. Another difference is that USB-C cables are reversible, which means there's no "up" or "down" side; you can just plug them in. is sometimes insufficient to power external hard drives, technology is advancing, and external drives gradually need less power, diminishing the eSATA advantage. Proprietary, hazardous Existing for specific proprietary purposes, not inter-operable with USB-IF compliant equipment and possibly damaging to both devices when plugged in.For a product developer, using USB requires the implementation of a complex protocol and implies an "intelligent" controller in the peripheral device. It has evolved into a standard to replace virtually all common ports on computers, mobile devices, peripherals, power supplies, and manifold other small electronics.

Most USB Type-A plugs are found at one end of many different kinds of USB cables, each designed to connect the host device to some other device that also supports USB, usually via a different USB connector type like Micro-B or Type-B.
