Hey guys I can't seem to find a section for newer PC hardware but I figured someone else may have seen this.

I recently upgraded to an AM5 CPU and motherboard with USB 4 support. The weird thing is, when I have USB 4 active in the BIOS, device manager has exclamation marks for PCI express downstream switch port with regards to the USB 4 slots. When I disable USB4 in the bios it goes away. No driver updates have yet to fix this. The ports themselves work fine but I don't know if they will function at USB 4 speeds.
Anyone else have this happen?

It is possible to commit no errors and still lose. That is not a weakness, that is life.

Looks like ASUS just released a patch.

Yeah, one of their firmware updates seemed to fix it.

It's kind of saddening how ASUS went from being a top notch motherboard maker to selling overpriced gaming boards with mediocre post-sales support

Bear in mind I usually post to the forums using my old systems.

Heh, retro is mainstream, the 1996 USB 1.0 experience revisited.

Unicorn herding operations are proceeding, but all the totes of hens teeth and barrels of rocking horse poop give them plenty of hiding spots.
