Hello,
So, I've been having an issue with my PCI drivers, and it has been bothering me a ton. 3 devices show up: PCI Device, PCI Simple Communications Controller and Unknown Device. All of which have no drivers. Please provide me with drivers.
Device: HP ProBook 450 G1
OS: Windows 11 Pro
Solved! Go to Solution.

Hi:
You need these drivers:
PCI Device:
Realtek PCIe Media Card Reader Driver
PCI Simple Communications Controller:
Intel Management Engine Components Driver
Unknown device: Probably this one:
HP 3D DriveGuard Software
If sp71708 does not install the Unknown Device, please post the hardware ID for it so I can figure out what driver it needs.
Use this guide for how to find the hardware ID for a device:

You're very welcome.
That is the Intel Bluetooth device in need of a driver.
There are no W10/W11 drivers for that device on the HP or Intel websites but the driver from Dell works fine.
