Method 1. Reconnect the device to your computer.

As easy as it may sound, it can be the fix for your issue. Firstly, disconnect the device. Then make sure that the cables and connecting ports for the device are in good condition. You can do this by connecting the device to another computer, using the same cable to see if it works. It the cable is the culprit, you need to replace it with a new one. Check now to see if the device functions properly, using the following steps:

  • Press Windows key + R on the keyboard.
  • Type devmgmt.msc in the search box and click OK. This will open device manager.
  • Right-click on the device and select Properties.
  • In General, you will see a message indicating that the device is functioning properly or the error code 45 if the device still has issues.

Method 2. Troubleshoot hardware and devices.

Microsoft has a built-in troubleshooter for hardware and devices. This tool helps Windows find and repair faulty devices. To do this, use the following steps:

  • Click on the Start or Home button.
  • Click the Settings icon in the pop-up menu.
  • Navigate to Update and Security.
  • Click on Troubleshoot, click on Hardware and Devices under Find and fix other problems
  • Click Run the troubleshooter.
  • Windows will search for problems with your devices and try to fix them.

Run the troubleshooter to detect and fix your update issues.

Method 3. Update your device drivers.

This is the most important step because it has fixed this problem for many users:

  • Type devmgmt.msc in the search box present at the bottom left corner of your computer screen and press the Enter key.
  • This opens the Device Manager window.
  • Right-click on the device with the yellow triangle beside it and select Update driver.
  • Select Search automatically for updated driver software in the next window.

You can also just uninstall the device from your PC:

  • Follow the steps above to enter the Device Manager window.
  • Right-click on the device and select Uninstall.
  • This will remove the device from your system. Then restart your PC
  • Windows will automatically install the device with its recommended drivers when your PC restarts. Alternatively, you can download the drivers online from the manufacturer’s site. The con to this method is that you need to know the exact name and version of your driver because downloading and installing a different version will cause the device to malfunction.

Method 4. Download and install an driver update tool.

There are many tools on the internet which can easily search for outdated drivers on your PC and install the latest and manufacturer-recommended versions. I recommend you to download and install Auslogics Driver Updater, as it is very easy to use.

Wait until driver updates are downloaded.
