    cypress usb3 "the software for this device has been blocked"

    content.librarian

      I've installed cyusb3.sys onto Win 8.1 system.

         

      Driver version is 1.2.3.3.

         

      When I plug in the FX3 device, I get this message:

         

      "The software for this device has been blocked from starting because it is known to have problems with Windows.
      Contact the hardware vendor for a nex driver. (Code 48)"

         

      So, what's the next step?

         

      Screen captures are attached.
