At first intended for magnetic and optical drives, it has been extended to support flash drives. It has also been extended to support a wide variety of novel devices as many systems can be controlled with the familiar metaphor of file manipulation within directories.

The process of making a novel device look like a familiar device is also known as extension.

The ability to boot a write-locked SD card with a USB adapter is particularly advantageous for maintaining the integrity and non-corruptible, pristine state of the booting medium. Though most personal computers since mid can boot from USB mass storage devices, USB is not intended as a primary bus for a computer's internal storage.

However, USB has the advantage of allowing hot-swappingmaking it useful for mobile peripherals, including drives of various kinds.

Several manufacturers offer external portable USB hard disk drivesor empty enclosures for disk drives. These offer performance comparable to internal drives, limited by the current number and types of attached USB devices, and by the upper limit of the USB interface.

Another use for USB mass storage devices is the portable execution of software applications such as web browsers and VoIP clients with no need to install them on the host computer.

It also has optional DRM features.

MTP was designed for use with portable media playersbut it has since been adopted as the primary storage access protocol of the Android operating system from the version 4. The primary reason for this is that MTP does not require exclusive access to the storage device the way UMS does, alleviating potential problems should an Android program request the storage while it is attached to a computer.

The main drawback is that MTP is not as well supported outside of Windows operating systems. Human interface devices[ edit ] Main article: USB human interface device class Joysticks, keypads, tablets and other human-interface devices HIDs are also progressively[ when?

For mice and keyboards with dual-protocol support, an adaptor that contains no logic circuitry may be used: Device Firmware Upgrade[ edit ] Device Firmware Upgrade DFU is a vendor- and device-independent mechanism for upgrading the firmware of USB devices with improved versions provided by their manufacturers, offering for example a way to deploy firmware bug fixes.

The DWG has published three versions of audio device specifications: For instance, this can require syncing a The female connector mounted on the host or device is called the receptacle, and the male connector attached to the cable is called the plug.

The USB specification requires that the cable plug and receptacle be marked so the user can recognize the proper orientation.

USB cables and small USB devices are held in place by the gripping force from the receptacle, with no screws, clips, or thumb-turns as some connectors use.

The different A and B plugs prevent accidentally connecting two power sources. USB connector types multiplied as the specification progressed.

The connectors were different so that users could not connect one computer receptacle to another. The data pins in the standard plugs are recessed compared to the power pins, so that the device can power up before establishing a data connection. Some devices operate in different modes depending on whether the data connection is made.

Charging docks supply power and do not include a host device or data pins, allowing any capable USB device to charge or operate from a standard USB cable. Charging cables provide power connections, but not data. In a charge-only cable, the data wires are shorted at the device end, otherwise the device may reject the charger as unsuitable.A phone connector, also known as phone jack, audio jack, headphone jack or jack plug, is a family of electrical connectors typically used for analog audio signals..

The phone connector was invented for use in telephone switchboards in the 19th century and is still widely used..
