An "Unknown Device" in Device Manager usually refers to a hardware component on your Windows PC that doesn't have a recognized or installed driver. This can happen when a device is connected to the system, but Windows either doesn't know what it is or doesn't have the appropriate driver to communicate with it.
When you see "Unknown Device" listed in Device Manager, it typically means:
- The driver for that device is missing or corrupted.
- Windows couldn't automatically identify the hardware.
- A recently installed hardware component or peripheral needs a driver update.
