Windows 11 Pro with AMD 9800x3d. MB is Asus x870e-e. No m.2 in slots 1, 2, or 3. Gen 4 m.2s in slots 4 & 5. In Device Mgr, getting Code 51 on 2 PCI Express Downstream Switch Ports. Have downloaded the recent firmware update for my MB for ASM4242 (ASMx424X_FWUpdateV40013_u424241022200011AcmAPDV5). Ran it as Administrator. I don't see anything occur on the screen but get a message to reboot. USB4 is enabled in the bios. After boot, I still see the Code 51 for the two Switch Ports. Under USB Controllers, I see USB4 Root Router (1.0) firmware tab says "unknown Vendor, unknown Date, Version 0.1a". Driver is Microsoft version 10.0.26100.3037. The USB4(TM) Host Router (Microsoft) driver is 10.0.26100.3037. I can't find any device that would confirm the correct execution of the firmware update. I plugged a USB-C phone into both 40GB USB-C ports and the Code 51 still exists. Bios is the most recent (1003) and everything else is up-to-date as far as I can tell. Chipset is AMD v7.01.08.129.
These errors cause W11 Device Security-Core Isolation-Memory Integrity to turn off after a reboot. So have to disable USB4/ASM4242 in the bios. Found it in the AMD PBS bios page.
Any thoughts or how to fix this would be appreciated.
