If you rarely use the built-in SD slot and the driver issue causes boot delays or error messages, disable the device in Device Manager instead of fighting it. External USB 3.0 card readers are cheap and often faster anyway.

If you are seeing an unknown device labeled "USB2.0-CRW" in your Device Manager on Windows 11, it is almost certainly the internal SD Card Reader (often made by Realtek or Ricoh).
