Base System Device missing WIndows 11

[JBinFla]

I upgraded from Windows 10 (what laptop came with) to Windows 11 and all was well.  Recently I did a "clean" reinstall of Windows 11 and there is one missing device driver showing in Device Manager.  Below is the hardware ID's listed for it.  I am unsure how to figure out what this is, and what driver I need to get Windows to recognize it.  Can you help?

Thank you!

Hello, installing HP Support Assistant and all the drivers did not help. I finally found what to do, sorry I’m on my phone so can not provide link. 

the answer is that I was missing Intel chipset drivers. I found something on the Intel website that was titled something like “Intel chipset drivers .inf install” and it installed all the .inf files for Intel chipsets (all I believe as I didn’t have to select which chipset I have). Once I installed this and rebooted all was fine and recognized.
