HP ProDesk 400 G3
Microsoft Windows 7 (64-bit)

Fresh installed Windows 7 64-bit with all latest updates. Problem is that I cannot get USB ports to work. Error is:

 

Error code 52: Windows cannot verify the digital signature for the drivers required for this device (Intel(R) USB 3.0 eXtensible Host Controller)

 

I have tried everything that I can think of. I have tried with drivers download directly from Intel and drivers that HP offers for this model. New and old versions.

 

 

Every other driver installs just fine.
