      Create a new String Value and name it UpperFilters. Close registry editor and restart your computer.

    I had the same error but no UpperFilters/LowerFilter values in the registry.
    My problem was likely corrupt drivers for the usb.
    I had to safe boot to command prompt (otherwise you can't replace/delete drivers) and replace the following drivers (copied from another computer) in the C:\Windows\System32\drivers directory.
    hidclass.sys
    hidparse.sys
    hidusb.sys

    Hope that helps. Spent a lot of time searching on the web but couldn't find this solution before.

    :D I was in disbelief about this working at first. However, it does! I'm posting here because this is still an issue with Windows 10, and this fixed my USB conflict.

    I had moved a Windows 10 install over from an AMD based laptop into a laptop with an intel CPU. Navigated to the mentioned registry entry, and removed the Upper Filters that referenced an AMD driver (USBFilter.sys) that was trying to force itself on my new intel based drivers.

    In hindsight, the hard drive actually moved over with little issue and I had to install the drivers that corresponded with the Dell Laptop I moved the drive into. However, I had a conflict on the USB, and after inspecting the driver, Windows 10 wanted to use USBFilter.sys, which was for an AMD based chipset, even though the system showed it was now using an intel based chipset for the USB drivers. No amount of uninstalling & reinstalling fixed the issue. Also, renaming the drivers & letting Windows replace them also didn't fix the issue.

    I also deleted the upper and lower filters. I know that programming is not an easy task, but come on these a huge companies with thousands of programmers. Microsoft could have an auto fixer for "Code 39", just alert the user first that registry changes by admin are required to fix this. Background: Happened on a Dell Latitude E5440, upgraded from Windows 8, to 8.1 to 10. One day after updating the Intel drivers using the Intel upgrader, then the Dell upgrade lastly the windows update to the Intel 8 series USB ports. The next day many laptops had no USB connectivity and "error 39"

    I can use my keyboard again!!
    just removing the lower filter data and refreshing device manager for hardware changes did it.
    I had to find my old ps/2 adapter to even use my mouse.
    glad I keep it around.
