Thanks. I didn't realize I could downgrade bios by simply flashing the older one. After switching to F9i, the USB errors in dmesg disappeared, and the system (11.5) has been up for 2 hours without freezing. Looks good so far, but will report back if the problem reoccurs.
I did not say there was anything wrong with your 0.7.6, or any other version.
In my post I was assuming the OP was swapping between 11.2 and 11.5 - because that was what they stated. Also in my post I pointed-out macOS version compatibility in the first sentence, but for Big Sur was not sure why the distinction was being made in the config.plist.
Uptime has been 4 hours and still good. I'll report back tomorrow, but it appears promising so you might want to give a try too.
Glad to hear it. Monterey is awesome. With OpenCore 0.7.1 it has been a smooth update on Z390 Designare.Would like to thank @UtterDisbelief , @bh1cqx, and @CaseySJ for their help. It appears that the culprit was the F9J BIOS version which has been downgraded to f9I. After about an hour or so of use; I have all USB, and wifi functionality on 11.5 . Hopefully Monterey will be a smoother transition!

Apple’s WWDC video provides a very good summary of Monterey. When we actually download and run it, it ceases to be academic and becomes real — something we can actually experience rather than just imagine. Monterey is an incremental update over Big Sur, but a very welcome one nonetheless.I am curious, what's so awesome in Monterey compared to Catalina or Big Sur?
At one point, I will need to upgrade from Mojave. Checking my options once in a while.
