Reasons For Unknown Devices Shown in Windows 11 Device Manager
The main reason for unknown device issues in Windows 11 is the absence of correct drivers installed on the system. This can occur due to faulty, corrupted, or outdated driver programs. Additionally, the latest driver files that Windows attempts to install after a new system startup may fail to be recognized by the operating system.
Another factor contributing to unknown devices is that some peripherals connected to the PC via USB ports, such as printers and scanners, require users to manually install their drivers.
Furthermore, the execution of Windows update procedures may inadvertently remove essential drivers or replace them, leading to the appearance of unknown device alert messages.

How to Install the Driver Manually in Windows 11
