Sometimes, you might encounter the USB driver error code 52: Windows cannot verify the digital signature for the drivers required for this device. Luckily, you can fix it by yourself. In this article, MiniTool Partition Wizard puts together some solutions to this issue and hope you can benefit from them.

Windows Digital Signatures

Based on Microsoft public key infrastructure technology, the Windows digital signatures are implemented to verify the identity of the software publisher or the driver vendor. The digital signature can protect your Windows from potential threats and infections of some malicious programs.

According to the explanation from Microsoft, Windows uses a valid digital signature to verify some information, including:

  • The file, or the collection of files (such as a driver package), is signed.
  • The signer is trusted.
  • The certification authority that authenticated the signer is trusted.
  • The collection of files was not altered after it was published.

In order to be installed and run on the latest Windows operating system, the drivers and programs must be digitally signed. However, there are still some legitimate programs or drivers that are not signed, and you may encounter certain problems while installing them.

About Windows Cannot Verify the Digital Signature Code 52

Sometimes, your USB ports might fail to recognize any hardware connected to your device, and you will see the error code 52 in the properties of the USB driver. The USB driver code 52 is a typical error related to the digital signature. It commonly occurs after updating or upgrading Windows and comes up with the following error message:

Windows cannot verify the digital signature for the drivers required for this device. A recent hardware or software change might have installed a file that is signed incorrectly or damaged, or that might be malicious software from an unknown source. (Code 52)

Besides, you might receive some other different error messages related to Windows digital signature, such as “Windows cannot verify the digital signature for this file. (0xc0000428)”, “Digital Signature not found”, and so on.

If you receive the digital signature error unluckily, take it easy. Some feasible solutions reported by the users are listed in the following contents, and you can work your way down the list until you fix the issue effectively.

Fix 1: Modify Windows Registry

In most cases, this issue is caused by 2 registry entries named UpperFilters and LowerFilters, and some users have fixed the problem simply by deleting them. So, if you receive the “Windows cannot verify the digital signature for the drivers required for this device” error message, try deleting these registries at first. The steps are listed below.

Note: This is a risky solution as any improper operations for registries might bring unrecoverable damage for your system. Therefore, you had better back up your Windows registry in advance, so that you can restore the registry to the original status if this solution doesn’t work.

Step 1: Press Windows + R to invoke Run window. Type regedit and click OK to open Registry Editor.

Step 2: Navigate to the following path: ComputerHKEY_LOCAL_MACHINESYSTEMCurrentControlSetControlClass{36fc9e60-c465-11cf-8056-444553540000}.

Step 3: Keep the {36fc9e60-c465-11cf-8056-444553540000} key selected, and find the UpperFilters and LowerFilters entries in the right pane. Right-click them and choose Delete.

Step 4: Click OK to confirm the operation. Restart your computer and check if the error code 52 disppears.

Fix 2: Update or Uninstall the Problematic Driver

If this is just related to a specific device driver, perhaps the problem lies on the driver itself. In this case, it should be helpful to update or uninstall the problematic driver. You can follow the instructions below:

Step 1: Right-click the Start button and choose Device Manager to open it.

Step 2: Double-click Universal Serial Bus controllers to expand the category.

Step 3: Locate the problematic USB driver. Commonly, the device driver which runs into the error code 52 will be displayed with a yellow exclamation mark in Device Manger, and it may be named as Unknown USB Device.

Step 4: Right-click the problematic driver and choose Update driver.

Alternatively, you can also choose to uninstall the driver, which has effectively removed the USB error code 52 for some users. Just right-click the driver, choose Uninstall device, and click Uninstall to confirm the operation. Then, restart your system, and the default driver will be reinstalled automatically.

Fix 3: Use System File Checker Utility

The corrupted or missing system files could also trigger the “Windows cannot verify the digital signature for this file/driver” error message. To resolve the problem, you can use the built-in System File Checker utility referring to the tutorial below.

Step 1: Open Run window.

Step 2: Input cmd and press Ctrl + Shift + Enter to run Command Prompt as administrator.

Step 3: Type the command sfc /scannow in the console and press Enter to execute it.

Then, this tool will start scanning your system files and automatically replace the problematic files with a fresh cached copy. All you need to do is to wait patiently until the process is 100% completed. After that, restart your device and check if the USB error code 52 is resolved.

Fix 4: Scan for File System Errors

It’s said that this issue might have something to do with the file system error. So, you can try scanning your drives for file system errors and fixing them.

To do that, you can use the CHKDSK tool. Just launch Command Prompt with administrative privileges, input the command chkdsk e: /f, and press Enter. Restart your computer after the process is completed.

Tip: You need to replace e: with the drive letter of the partition you want to scan for. If you execute the command chkdsk /f without a drive letter, this tool will automatically check and fix the current drive (the system drive in almost all cases), which will require a reboot.

Windows Cannot Verify the Digital Signature FAQ

Can I install a driver without a digital signature?
To install a driver and make it work properly on your computer, the driver should be officially signed. But sometimes, you may want to install a drier without a digital signature. Yes, you can force an unsigned driver to install, but it may take some time. For the detailed information, you can check this guide.
How do I fix an invalid digital signature?

If you encounter the invalid digital signature installation error, you can try the following solutions:

  • Make sure the downloaded executable is unblocked.
  • Install the certificates manually through the properties of the executable file.
  • Consult your group policy admin to temporarily disable restriction for the authentication of certificates.
What is the difference between signed and unsigned drivers?

The signed driver with a correct digital signature indicates that it is not damaged, corrupted, manipulated, or changed, and it is safe to use. It can be installed and work properly on Windows.
