Solved!

Unknown Device after Windows 10 installation

HP Recommended
Pavilion 11 x2
Microsoft Windows 10 (64-bit)

After upgrading to Windows 10 my device manager shows that my PCI encryption/decryption controler has no drivers installed.  I tried using the HP support website to obtain all the drivers but it still wont load the Intel Trusted Execution drivers and now shows "unknown device" with no drivers loaded.  How can I resolve this?

Hi:

 

If your notebook has an Intel processor...

 

Try this version:

 

http://h20564.www2.hp.com/hpsc/swd/public/detail?sp4ts.oid=6431933&swItemId=ob_128754_1&swEnvOid=419...

 

Also, please post the hardware ID for the unknown device.

 

To find the hardware ID, go to the device manager, and click on the unknown device.

 

Then click on the Details tab at the top of the unknown device window.

 

Now you should see a Property drop down list and it will be set to Device Description.

 

Drop down on that list and select the 3rd item (Hardware ID's).

 

Post the top string of characters that you see in the window.

Thank you for your advice.  I tried the driver you provided a link to but it didn't change anything (except to tell me it was an older version).  The string you asked me to copy is:

 

ACPI\VEN_INT&DEV_3400

 

Hope this helps.

You're very welcome.

 

The reason the driver I posted didn't work is because the Intel TXE device has been properly installed.

 

The unknown device is a totally different animal, and needs this driver...

 

This package contains the driver that enables the Intel DynamicPlatform and Thermal Framework firmware. Intel Dynamic Platform andThermal Framework provide system temperature and power utilizationinformation for the system thermal protection to function properly.This package is provided for supported notebook models running asupported operating system.
