Hey Guys,

I recently updated my AMD chipset drivers and, out of curiosity, checked "Device Manager" to confirm the installation. Most of the items that begin with "AMD..." show the driver provider as "Advanced Micro Devices, Inc.", which seems correct.

However, I noticed that two specific items "AMD PCI Express Downstream Switch Port" and "AMD PCI Express Upstream Switch Port" show "Microsoft" as the driver provider instead.

Is this normal behavior, or could it mean the chipset driver didn’t install properly? Would appreciate your help! Thank you!
