Help identify Unknown Device in Device Manager on HP EliteBook 840 G6

[JPSRT8]

I have managed to locate all but the following driver for the HP EliteBook 840 G6 devices we are deploying in our company:

Any clues to what this device could be and where I could find the driver for it?

Thank you in advance.

Hi:

Doing a search of the hardware ID, led me to this discussion...

On your notebook,the 'Intel TXT Authenticated Code Module' is apparently installed by this driver...

This package provides the Trusted Execution Technology (TXT) Driver for the supported computer models running a supported operating system.

What baffles me is the device is listed in the driver setup information file, but not the hardware ID you posted.

%ACM_SINIT.DeviceDesc% = Needs_NO_DRV, ACPI\INT_WHL_SINIT

INTEL="INTEL"
ACM_SINIT.DeviceDesc="Intel(R) TXT Authenticated Code Module"
