Performing Driver Installation

One of the factors that cause the problem in our title is that Windows cannot automatically identify the driver correctly. In such cases, the above are tried and the right driver is searched for the situation. When Google searches are insufficient, necessary searches are made with driver finding programs.

Some of the installed drivers may work incompatibly. In such cases, previous drivers need to be tried one by one. If you perform the setup process, the clean installation option sometimes appears when starting the installation. With this option, the ones you previously installed will be properly removed.

Resolving Unknown USB Device with System Restore

This method generally provides solutions to software, driver and program-related problems. It has provided solutions to a wide variety of problems since ancient times.

System restore is a feature in the Windows operating system and can be used to fix errors and problems occurring on your computer. This feature restores your computer's current state by going back to a date when your computer was working before.

You can follow the steps below to perform a system restore:

  1. Open the “System Restore” option from the Start menu.
  2. Click the “Next” button and a window will open showing a list of system restore points.
  3. Select the date you want to restore. This is the date your computer was previously working.
  4. Click the “Next” button to confirm the date you selected.
  5. Check the date and time your computer will be restored.
  6. Click the “Next” button and click the “Restore” button to start the restore process.
  7. After the restore process is complete, your computer may need to restart.

System restore restores only system files, without affecting any programs or files on your computer. Therefore, after the system restore process, the programs you installed or the settings you changed will not be restored.

System restore can be an effective method to fix errors and problems occurring on your computer. However, it may not always work and in some cases it may not solve the problem. Therefore, before performing a system restore, it might be a good idea to back up your files and save your important data somewhere else.
