USB & Bluetooth driver signature's cannot be verified (Code 52) RRS feed

  • Question

  • I need some help with a Windows 7 (x64) system where bluetooth and usb devices have suddenly stopped working. When I go into device manager I see that my Intel USB 3.0 extensible host controller and my Intel Wireless Bluetooth show exclamations on them. They both report that "Windows cannot verify the digital signature for the drivers required for this device".  

    This machine has been working fine for a while but suddenly stopped working correctly earlier this week.  So far I have uninstalled recently installed MS patches. I installed the most current version of the drivers from Intel for these devices. I've also ran sigcheck against both drivers and confirmed that they are signed. 

    As a work around, I use F8 and boot with driver signing verification turned off but that is certainly not ideal as I have to remember to do so every time the computer is restarted. Anyone have suggestions for a permanent fix?

  • I ended up reimaging the PC and then the drivers loaded correctly. No idea why they failed in the first place though.
