Unknown Base System Device

Apologies if this is the wrong place to post- I'm at a dead end and cannot figure this out.
- ROG Strix z490-E Gaming
- i7 10700k
- Gigabyte RTX 2080 Super (Gaming OC)
I recently swapped my motherboard from a MSI z490 board to the ASUS ROG Strix z490-e Gaming, Everything works fine- yet after swapping two unknown PCI Devices appeared.
I've double checked all Asus BIOS/Drivers/everything is up to date. I did figure out SOME things about these mystery PCI Devices but cannot resolve the issue- crying uncle and asking for help.
Device Hardware IDs
- Both of the 'PCI Device' displayed have identical Hardware IDs
Device Instance Path
PCIVEN_8086&DEV_06E9&SUBSYS_86941043&REV_003&115 83659&1&A9
The only EXACT Match I could find was on a random website in foreign language where someone was listing system specs. No idea if accurate but shows as:
- Intel(R) LPSS: I2C Controller #0 - 06E8
If I do a more board search of '8086&DEV_06E9' it appears this is an Intel Driver.
- Intel(R) Serial IO I2C Host Controller
I cannot seem to find an exact match for this driver from Intel - only things with a similar name from 2015. I did find some matches but from 3rd party sites I'd rather avoid.
I tried anything I could find from Intel and nothing has fixed the issue. Still see these two PCI Devices. Am hoping someone here has the same issue and can help!

We went ahead and set one up, formatted it and loaded XP (exercising our downgrade rights!), but I found a device in hardware manager that I cannot find a driver for, nor can I figure out what it is. It shows up under 'Other Devices' simply as 'Base System Device', of course with the yellow question mark and exclamation point, but of which are. 1) In Device Manager, right-click the device and click Update Driver Software. 2) Click Search automatically for updated driver software. Then Windows will search and find the driver for you. 3) Reboot your computer and check to see if the Base System Device driver issue is fixed.

To solve the problem, we can just update the driver in Device Manager, or re-install the device driver if you want. There are three methods available.
