X570 Aorus Master F30 BIOS kills USB

[Bonzo]

After updating my X570 Aorus Master BIOS from F22 to F30 I noticed that the keyboard and mouse were dead. Other USB devices were also not working. The issue only affected certain USB ports so I was able to plug the mouse\keyboard into a working set of ports to see if any BIOS settings were to blame.

After various checks I've had to restore my old F22 BIOS - all is now fine.

So, a warning, F30 looks like it has serious issues.

Greetings,
This might not be the F30 BIOS entirely, as it might be the BIOS or settings in conjunction with your specific hardware.  Example: Fast and Ultra Fast Boot (if enabled, try disabling this)

Over time, we have seen similar issues where only the USB 2 ports work during POST or in a preboot environment.  Preboot behavior can also be affected by your OS.

Chipset+USB 2.0 Hub:
8 x USB 2.0/1.1 ports (4 ports on the back panel, 4 ports available through the internal USB headers) 

Using adapters, etc. can also cause strange behavior.  Not saying these apply in your case, but recommend they be ruled out if having F30 is that important.

A review of CPU support shows everything currently available being supported with BIOS F20 and <.   F22 improves memory compatibility.  If you aren't having issues, you don't need it. 

F30 potentially improves latencies between CPU cores.  3% ~ 14% depending on which CPU you own...  this timing is measured in nano-seconds.  Keep in mind it's "potentially" not "it will".  So in a best case scenario you might see up to 9.0 nano-second improvement.  Do you think you will actually be able to perceive this? (Even if there was this level of performance increase).  Then F3x comes out and it all starts again.   

Using overly aggressive BIOS settings can also introduce weirdness.  So you'll need to do more testing if you want to confirm an issue, and state with any level of certainty that a problem with F30 might exist.

I've no what you may label as aggressive settings in place. The same settings have been in place and have been generally rock solid through quite a few BIOS versions so I've no reason to believe the issue is down to anything other than F30.

I re-upgraded to F30 again yesterday and the exact same USB issues instantly returned. Nothing I found in the BIOS configuration resulted in fixing the failed USB port. I'm back to F22 and all is good.

The only other issue I've experienced pre-F30 is BIOS settings being lost after power loss.

OK - it looks like the process of updating the BIOS using the @BIOS tool was causing the failure. After two attempts using @BIOS and losing USB ports all was fine when I updated the BIOS from the QFlash tool.

Looks like I won't be using @BIOS again.

I bet the non working ports were the front ones.
Happens to me after each update.
Absolutely not the fault of @bios

The fix: cut PSU power for 1 minute. Power on. Working USB.

Greetings,
So no apparent issue with F30..  and the statement in my earlier post about "needing to do more testing if you want to confirm an issue, and state with any level of certainty that a problem with F30 might exist" was correct.

Qflash is indeed the safest bet for BIOS update.  Glad you figured it out.
