PRIME X470-PRO BIOS 5406
Update AM4 combo PI 1.0.0.4 patch B
And got in a lot off trouble, storage devices reacted slow, LAN adapter didnt work, and my Creative AE-5 didnt work!
When i looked in Device manager i noticed an error in my ASMedia device and varios other USB controller error's.
Also loading of my Ryzen Master didnt work!
Finally cleared the CMOS and reflashed the previous bios again (phew!).
When i google around, i found more people experiencing these problems with other mainboard brands and the 1.0.0.4 patch B update.
