Hi patof, I have made a thread for you here.

ASROCK X870E PHANTOM NOVA - USB Setup/Install Issues - RESOLVED

Hello All,

I just finally upgraded my own rig(2020) as well my Daughters work PC with new AMD 9000 series CPU and AMD MB. I have 3 more new AMD CPU waiting for Black Friday MB/Memory sales to update the rest of her family.

My own rig - ASROCK X870E Phantom Nova with 9950X3D on WIN11 23H2 - was giving me fits trying to get the USB4, PCI Express Downstream Switch Port and an Unknown USB Device (Failed Descriptor) sorted.

I had started with using the Auto Driver Installer and continuing with the rest of the Drivers from the ASROCK Nova page.

I reinstalled both sets of Chipset Drivers several times until the Auto Driver Installer returned no results - it looks like the Auto Driver may link to a newer Chipset version.

Still no joy with either the PCI Express Downstream Switch Port or USB4 or the UNK USB item.

I was also in the middle of initial PBO2 tweaking and read that SOC voltage could affect USB ports/signaling - initial BIOS settings have SOC @ 1.2Volt and other guides/testers have recommended 1.10 > 1.15.

As soon as I reset to 1.10 the USB 4 driver and the PCI Express Downstream Switch Port cleared but the UNK USB still would not.

I kept searching here and across the web and finally found a post with the simplest fix for the Unknown USB Device - Power Cycle the PSU (Turn the PSU Power button off/on and reboot).

As soon as I shutdown and flipped the PSU Power Button off and back on and rebooted the UNK USB item cleared.

I then continued to final PBO2 settings and everything is still good at a final SOC @ 1.15V (suggested by a tester for the 3.40 BIOS).

This is what sorted a maddening first install and I'm posting if it helps anyone else with these issues.

	Welcome decapfour. So what kind of system are you looking to build? When it comes to selecting a motherboard it helps to know what the system will be used for, what kind of budget you are looking at and what features you need (wifi, 2.5g LAN etc).
