Original Title: Error Code 52 - USB ports not recognizing connected USB devices

I have recently purchased a new laptop with Windows 7 and had no initial problems connecting USB devices (mouse, hard drive, camera etc.) to the ports. Since installing a number of windows updates none of my USB ports will now recognize any hardware that is connected to them.

The error code is quoted as follows **"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".**I have been into Device Manager and notice that each USB icon has a yellow exclamation mark icon next to it. I have uninstalled each USB port and scanned for hardware changes which has no positive affect. I have also tried to 'Update driver software' in device manager and again this tells me that the driver is up-to-date for each USB port.

Any help would be much appreciated.

Hi slark101,

Boot into Advanced Boot Options and disable driver signing checking.

The Advanced Boot Options screen lets you start Windows in advanced troubleshooting modes. You can access the menu by turning on your computer and pressing the F8 key before Windows starts.

Disabling driver signature enforcement has helped a lot of users in fixing the issue.

You may also delete the USB "Upper Filter" & "Lower Filter" Entry and check if that helps.

Before we go any further, please first backup the Registry.

Important This section, method, or task contains steps that tell you how to modify the registry. However, serious problems might occur if you modify the registry incorrectly. Therefore, make sure that you follow these steps carefully. For added protection, back up the registry before you modify it. Then, you can restore the registry if a problem occurs.

    Hi Craig,

    To further assist you with your query, we'd like to know more information:

    • What is the exact error message that you received when you got the blue screen error?
    • Which version of Windows are you using?
    • Did make any changes to your computer?

    Looking forward to your response.

    When I booted into Advanced Boot Options and disabled driver signing checking, I could then see attached USBs. My account has Administrator access.  When I gave the laptop back to the student that was using it, he couldn't see USBs attached.

    I restarted the laptop booting into Advanced Boot Options and disabled Driver Signing Checking, when the laptop completed its startup, I had the student logon and he still couldn't see his connected USB.

    So, my question is the same as someone else's, is it necessary to use the Advanced Boot Option everytime one logs on from here on out as long as they have Admin rights?

    I tried deleting the UpperFilter & LowerFilter, however, on restart the laptop kept booting into the "Blue Screen of Death."

    Isn't there another way to fix this?

    I didn't find UpperFilter or LowerFilter at those locations.
