A good example is when a computer user enters data in a word processing program using a keyboard and mouse at the same time. The protocol of the host controller combines the communication process of several devices in order to create an efficient and simultaneous data transfer. Recognition of standard devices like the keyboard and mouse by the operating system is usually done automatically by the host controller. The xHCI has been designed for improved speed, power, and efficiency than its predecessors. Other types of host controller interfaces include the enhanced host controller interface (EHCI), which is rated super-fast by publicly specified standards, and the newest host controller standard, called the extensible host controller interface (xHCI). The universal host controller interface (UHCI) from Intel® supports USB 1 in both fast and slow speeds. The open host controller interface (OHCI) is the standard for most and even supports USB 1.1. There are several types of USB host controller interface that support different types of USB ports. Every USB device communicates with the computer’s operating system in a standard programming language, such as C++.
The operating system relies on the USB host controller in order to avoid having to install individual drivers for every device connected. Most modern computers have hi-speed host controllers and many older computers can have a host controller easily installed in an open slot on its motherboard.Ī hi-speed USB host controller maintains a connection between such devices as a keyboard, mouse, modem or printer and ensures that the computer's operating system recognizes the device. A USB host controller manages the communication between peripheral devices and the computer system. Additionally to the USB problem, my computer doesn't shut down anymore when I tell him to. I also resetted the CMOS in case something in the BIOS should've changed, still not effect. The USB connection is an input and output port that comes standard with most computers and a variety of other digital equipment that allows data to be transmitted through a cable or any other form of direct connection. It does say in the device manager, that the USB-xHCI-Hostcontroller has a code 10, but even after a clean install of windows I wasn't able to solve the problem.
A Universal Serial Bus (USB) host controller is an interface that allows an enabled piece of hardware to interact and communicate with a particular piece of software.
