The label "unknown" often appears in hardware lists because this specific Product ID ( FA00 ) is used for hardware. Unlike branded peripherals that have specific names in a driver database (e.g., "Logitech Mouse"), generic card readers often show up as "Unknown" or "Generic" until a specific driver is installed or the device class is identified.
