What is the USB to Serial Interface Controller Windows Driver?
A USB to Serial Interface Controller is a hardware device or adapter that enables communication between a computer's USB port and devices that use a serial communication interface, typically through an RS-232 serial port (often found on older hardware like printers, modems, and other industrial devices). These adapters are commonly used when you need to connect older equipment that only has a serial port to modern computers that do not have serial ports but do have USB ports.
The USB to Serial Interface Controller driver is essential for the operating system to recognize and communicate with the USB-to-serial adapter correctly. It allows the computer to treat the serial interface as a virtual COM port, enabling software to send and receive data via serial communication.
