I just built a new system with this mobo and Ryzen 7800x3d. The bottom 3 USB ports do not work (E1-3). I have a NVME in m.2 A and D. I do not see anything in the manual about them not working or a condition for them not working if hardware is plug in or used in another area. They also show enabled in the bios. I have no issues showing in the device manager. I have the latest BIOS, AMD chipset drivers and WIN 11 is fully updated as of this writing.
Any ideas? I hate to RMA the board if I missed something..
