The Conexant 2388x Device is a video capture device, typically used for TV tuners, video capture cards, and sometimes webcams or other video input hardware. The Conexant 2388x is a chipset used in many different devices to capture analog video signals and convert them to a digital format for processing by the computer. It is often found in TV tuner cards, video capture cards, and even in some digital video recorders (DVRs).

The Windows driver for the Conexant 2388x Device enables your computer to recognize and properly interact with the device. Without the driver, Windows will not be able to communicate with the Conexant hardware, and features like watching TV, recording video, or capturing footage from an analog source (e.g., a VHS player or TV antenna) will not work.
