A USB composite device driver is a software program that enables a computer to communicate with a USB composite device, which is a device that combines multiple functions within a single physical unit. Examples of USB composite devices include printers with built-in scanners, USB hubs with built-in card readers, and smartphones that can function as cameras and storage devices.
The USB composite device driver allows the computer to recognize and interact with each individual function within the composite device as if it were a separate device. This enables the user to access all of the features of the composite device without needing to install multiple drivers.
The driver typically comes pre-installed with the operating system, but it may need to be updated or reinstalled if there are issues with the device's functionality. This can be done through the device manager in Windows or the system preferences in Mac OS.
