It then requests identification from the device and appropriately configures the drivers. In operation, the USB host automatically detects when a new device has been added. In terms of performance, USB 1.1 enabled a maximum throughput of 12 Mbps, but with the introduction of USB 2.0 the maximum speed is 480 Mbps. However, since its introduction, the applications for USB have widened and it has been used for many other purposes including, including measurement and automation. The basic concept of USB was for an interface that would be able to connect a variety of computer peripheral devices, such as keyboards and mice, to PCs. Raw data transfer rates of 5 Gbit/s for USB 3.0 and 10 Gbps for 3.1. In addition to this a variety of other peripherals adopted the USB interface, with small memory sticks starting to appear as a convenient way for transferring or temporarily storing data. USB 1.0 was widely adopted and became the standard on many PCs as well as many printers using the standard. This was followed in January 1996 by USB 1.0. The first proper release of a USB specification was Version 0.7 of the specification.
The USB interface was developed as a result of the need for a communications interface that was convenient to use and one that would support the higher data rates being required within the computer and peripherals industries.

USB uses a serial form of data transmission, and it allows up to a maximum of 127 different peripherals to be connected to a single port - this would require the use a a hub or hubs to enable this number to be connected.
Having a standard type of interface port significantly increases the flexibility of computers because it is not necessary to have cables for the variety of ports that used to be used. USB is now the most common form of computer interface and it has taken over from other forms of computer interface ports that normally tend to be much slower.
USB, or Universal Serial Bus is a data interface used with computers enabling the computer to send and receive data as well as providing power to some peripherals like disc drives, Flash memory sticks and the like so that separate power sources are not needed for each item. Whilst USB provides a sufficiently fast serial data transfer mechanism for data communications, it is also possible to obtain power through the connector making it possible to power small devices via the connector and this makes it even more convenient to use, especially ‘on-the-go.’ Selection of USB connectors, adapters and cables What is USB The Universal Serial Bus, USB provides a very simple and effective means of providing connectivity, and as a result it is very widely used. Its combination of convenience and performance has meant that it is now one of the most widely used computer interfaces. USB interfaces are found on everything from personal computers and laptops, to peripheral devices, mobile phones, cameras, flash memory sticks, back up hard-drives and very many other devices. USB, Universal Serial Bus is one of the most common interfaces for connecting a variety of peripherals to computers and providing relatively local and small levels of data transfer.
