To understand the demand for this driver, one must first understand the role of a driver itself. A driver acts as a translator between the operating system (Windows 10) and the hardware device (the ALP204). Without this specific instruction set, Windows 10 may recognize that a device is plugged in, but it will not know how to interpret the data it sends or how to control its functions.
