Elitebook 840 G5 PCI Bridge driver

[JenniJ]

Hi,

I am looking for a driver for a PCI to PCI Bridge device which is showing in device manager as not having a driver installed.

The device ID is PCI\VEN_8086&DEV_15DA&SUBSYS_00008086&REV_02.

We have deployed this model of machine previously with no issue and the driver packs installed in SCCM worked fine. However some hardware must have changed in the latest batch we have purchased as they are showing this extra device.

I have tried every driver I can find on the support site for this model, but nothing has helped. I can't even find a description of what this piece of hardware actually is.

There was a suggestion on one of the forums that this was a driver for a Thunderbolt 3 dock, but I have tried this driver (out of desperation) to no avail. There is no dock attached and no thunderbolt port on the laptop.

Any help is much appreciated.

Thanks

Try using HP Image Assistant (HPIA) on your system.

The tool will examine your current image and see if there are any recommendations for fixing potential issues.

What version of Windows 10 are you using?

Managed to find the issue - Was a group policy blocking the device installation.

For anyone with the same issue :

Computer policy > Administrative Templates > System > Device Installation > Device Installation Restrictions > Prevent installation of devices that match any of these device IDs > PCI\CC_0C0A.

This was implemented due to the following article from Microsoft :

https://support.microsoft.com/en-gb/help/2516445/blocking-the-sbp-2-driver-and-thunderbolt-controlle...

This didn't affect any of the previous models, so some hardware has been added in the G5's (we had it on 840 G5 and 830 G5).

In order to maintain security after this group policy setting was removed, we made a change to the BIOS settings of the machines to only allow DisplayPort and USB through the thunderbolt ports.

Thanks you for your response.
