It is an industry standard developed in the mid-1990s that defines the cables, connectors and communications protocols used in a bus for connection, communication, and power supply between computers and electronic devices. Revit Furniture Family Downloads. USB was intended to standardize the connection of computer peripherals (including keyboards, pointing devices, digital cameras, printers, portable media players, disk drives and network adapters) to personal computers, both to communicate and to supply electric power. It has also become commonplace on other devices, such as smartphones, PDAs and video game consoles. USB has effectively replaced a variety of earlier interfaces, such as serial and parallel ports. USB flash drives are memory devices that are inserted and powered by USB ports.

They store information and data that needs to be easily accessed. These devices are portable and convenient for people on the go. USB ports are a common necessity for students as well as business employees or personnel. In addition to convenience, they range in storage capacities from 1GB to 64 GB, so end users are able to store as much information as small computers. A USB Series “A” plug The hardware that contains the host controller and the root hub has an interface geared toward the programmer which is called Host Controller Device (HCD) and is defined by the hardware implementer.

In practice, these are hardware registers (ports) in the computer. At version 1.0 and 1.1 there were two competing HCD implementations.

Compaq's Open Host Controller Interface (OHCI) was adopted as the standard by the USB-IF. However, Intel subsequently created a specification they called the Universal Host Controller Interface (UHCI) and insisted other implementers pay to license and implement UHCI.
