What is a USB host controller?
Universal Serial Burs is standard for input/output port for computer and digital device, allowing easy data transfer using direct connection or cable. The original standard version of the USB has been replaced by hi-speed versions. USB Host Host Host refers to hardware inside a computer that provides ports of USB functionality.
The USB first hit the market in November 1995, but the new standard had compatibility problems. These errors have been addressed and the subsequent version of the USB is now referred to as the "original" USB 1.1. Data transfer speed (DTR) for USB 1.1 was impressive at 12 megabitts per second (MBPS) and was designed to replace slower parallel and serial ports for peripheral devices. The first devices to be widely accepted for USB ports were keyboards and mice. Followed by printers, scanners, external tape units and other devices. USB 2.0MM boasts maximum data speeds of 480 Mbps, 40 times faster than the original USB. Computers thatThey support the old standard, required a new hi-speed host controller to take advantage of faster speeds. Devices created for the new standard 2.0, such as memory sticks and digital cameras, would set the default to old, slower transfer rates if connected to a computer with a USB 1.1 installed controller.
Him-Speed controller is built into modern computers, while older computers can be updated with hardware. The controller is cheap and can be purchased anywhere where computers are sold. It is a card that is easy to install in any available slot in the motherboard. The controller back plate provides two or more hi-speed USB ports.
To use USB 2.0, the computer and the device connected to the USB port must support the standard 2.0. Host host with hi-speeder cannot create USB 1.1 equipment at 2.0 speeds. Him-Quercostal Drivers JSicedly compatible, but for devices that require it, they are back to the slower 1.1 standard.
One of the many advantages of USB ports is that they can work in the Daisy chain and one controller can control several USB ports. If the computer does not have enough ports for user needs, you can add a USB hub. The hub is connected to a single USB port and offers a "bay" of other ports. However, some devices may require a direct port or a powered hub. Powered hubs have their own A/C adapters.
