In most cases, this driver controls the built-in SD card reader found on laptops (particularly older models from manufacturers like Lenovo, HP, and Dell). Even if your laptop is relatively new, it may use a card reader chipset that operates on the USB 2.0 standard. When Windows 11 installs updates or performs an upgrade from Windows 10, it sometimes fails to locate the specific vendor driver for this hardware, defaulting to a generic Microsoft driver that may not work correctly.
