Fix 2: Reinstall your device driver

When the error message says your hardware device is not connected to the computer, chances are your device driver is outdated or corrupted. In this case, manually reinstalling your device driver may help you out.

Step 1: Uninstall the device driver

On your keyboard, press the Windows logo + R keys simultaneously to open the Run box. Then enter devmgmt.msc and hit Enter.
In the Device Manager window, locate the device that’s giving you Code 45.
Right-click on that device entry and select Uninstall device.
Tick the checkbox for Delete the driver software for this device and click Uninstall (if you’re prompted for confirmation).
In Device Manager, click Action on the menu bar and select Scan for hardware changes. This should refresh the system, then reinstall the device and its corresponding driver.
Restart your computer.

Step 2: Reinstall device driver

If you’re on Windows 10 or later, Windows generally will download and install the genenric esstential drivers for your device after a reboot. So you can now open Device Manager to check if the device is present and the Code 45 issue has been resolved.

If the issue is still there, or your device isn’t working properly, you can try to install the latest device driver. You can do that manually, by visiting the device manufacturer’s website and downloading the latest correct driver for your system. Or you can do it automatically with Driver Easy.

Fix 3: Run the Windows Hardware and Devices Troubleshooter

Microsoft offers you a Hardware and Devices Troubleshooter to diagnose and fix hardware issues. So try this built-in tool if any hardware problems happen to your device. To use it:

On your keyboard, hit the Windows key and type power. When Windows PowerShell shows up and is highlighted from the list, click Run as Administrator.
Copy and paste msdt.exe -id DeviceDiagnostic in the Powershell, then hit Enter.
Now you should see the Hardware and Devices Troubleshooter. Click Next to continue.
Follow the on-screen instructions to finish troubleshooting.
Restart your computer and your problem should be resolved.

Fix 4: Run System File Checker

System File Checker (SFC) is a built-in Windows tool that scans and repairs corrupted system files. If you encounter the Code 45 issue in Device Manager, it’s likely that the file responsible for your device is missing or corrupted. So you should run SFC to fix the problem. To do so:

On your keyboard, press the Windows logo key. Then enter cmd.
Right-click Command Prompt to select Run as administrator, and then click Yes if prompted for permission.
Once you see the command prompt, type sfc /scannow and press Enter.
Windows will now verify the system files and automatically fix any detected issues. (If the command returns other error messages, check this Microsoft tutorial for further instructions.)
Once the verification is complete, exit the Command Prompt.
Reconnect your hardware device and see if it’s working properly.

Fix 5: Run CHKDSK

CHKDSK (Check Disk) is a command run utility used to check the file system and status of the system’s hard drives. Sometimes the hard drive’s problem could be the possible reason for Code 45. In that case, you can run chkdsk to fix your problem.

On your keyboard, press the Windows logo key. Then enter cmd.
Right-click Command Prompt to select Run as administrator.
The command prompt will once again display. Type in the command: chkdsk.exe /f /r and hit Enter.
Type Y to confirm that you’d like to perform the disk check the next time you restart your computer. Please make sure you have closed all of your applications first.

Note: Running a disk check could take some time to complete. So if you don’t have the time to run the disk check the next time you boot, you can skip it and reschedule again by following the steps above.

Once the disk check has been completed, open Device Manager and see if Code 45 has been fixed.

If this method doesn’t resolve your issue, don’t worry. There is something else to try.

Fix 6: Run a DISM scan

DISM stands for Deployment Image Servicing and Management. Running a DISM scan can help fix computer errors. Here’s how to run a DISM scan:

On your keyboard, press the Windows logo key. Then enter cmd.
Right-click Command Prompt to select Run as administrator.
Click Yes if prompted for permission.
The command prompt will once again display. Type in the command DISM /Online /Cleanup-Image /RestoreHealth and press Enter.
Wait for the scan to finish (it may take up to 20 minutes).
Restart your computer and relaunch Device Manager. Check to see if Code 45 has been fixed; if it has, then congrats! Otherwise, please move on to the next fix.
