Does anyone have a suggestion on how to install or have system recognise these two devices

PCI Device and SM Bus Controller.

I have installed all relevant software from Asus, tried windows update but still devices show up as unknown.

My MB is the Maximus XI Hero. I'm using the onboard Graphics and don't have the PIC slots used at the moment. The only thing I can think of is some setting change in BIOS. Any suggestions would be helpful, thanks.

Installing latest chipset drivers should fix the SM Bus Controller unknown device.
Also installing Intel Management Engine Interface driver should also fix the unknown PCI Device.
Make sure the downloaded drivers .zip package isn't blocked before extracting drivers and installing.

It is strange, the exact same thing is happening with the new Z490 boards. No driver available, for some reason will enable those exact same devices.. I suppose it will take some time for the folks responsible will give us a fix..

I have found windows update to be very good at finding hardware drivers. But another way is to get the hardware ID from the device properties and search for it in Google.

Selecting the relevant drivers from the Windows 10 Optional Driver updates fixed it for me.

Well Lord be hold.
I did a format again,
Reinstall windows, turned off armor crate from installing in bios.
Popped the instal disk for the motherboard.
Played around with suggestions mentioned here:
Go to Intel get the latest drivers, tried auto feature didn’t help (intels website says I all updated) LOL, downloaded chipsets from Intels website, tried the chipset INf download too, didn’t work, then downloaded current version of armorcrate and noticed it saying to update the chipset. So I did
Boom!!! Worked.*
