What Is A Usb Controller?

A USB controller is a device that manages the communication between a USB peripheral device and the computer. It is a small chip integrated into the USB peripheral device or the computer system that acts as an interpreter of communication signals between the peripheral and the computer’s central processing unit (CPU).

USB controllers enable a wide range of devices to be connected to a computer, including printers, keyboards, mice, webcams, and external hard drives, to name a few. USB controllers determine the data transfer rate, power supply, and the type of peripherals that are compatible with the computer’s USB ports. As a result, they have become an essential component of modern computer systems, providing users with a versatile and convenient way of connecting peripherals to their computers.
