HP elitebook 850 G2 unknow device

I am having an issue installing drivers for two unknow devices that is showing on my device manager.

One is showing as ACPI\INT3397\2&DABA3FF&2 in the device detail.
One is showing as {55BC022C-955B-4D87-A88D-D3E68CBEB2F4}\CT_27B961DB-3057-49BB-BD0D-ACA9FD8FF697\4&25444F6C&0&00

You can Always use HP Softpaq. It will automatically detect all driver and install them.

Have a read of this thread https://communities.intel.com/thread/61445

The second one can be solved by disabling the NFC in the BIOS.

The first one may be solved by a BIOS update.  

But have a read of the thread.

Have you downloaded and installed the chipset drivers for your OS for that PC, then rebooted, and after that installed the rest of the drivers?
