wondering if anyone has seen something like this:

asus x299 prime deluxe II
opencore 0.5.8
mojave 10.14.6 - all updates applied
USB kext under 15-port limit for all controllers
no port limit disable kext

USB mass storage is unreliable - if i move a lot of data to a USB-attached hard disk, eventually the port locks up, any processes trying to read or write the disk hang and are next to impossible to kill. sometimes i have to reboot the machine to restore sanity. internal NVMe disks work fine; the problem is only with external USB disks. this problem seems to exist on all the controllers in the machine.

i think i've had this problem since the beginning (july 2020) across multiple versions of 10.14, but i don't rely heavily on external USB disks so the problem was not obvious.

i don't find a lot on this from google so its got me wondering just what might be wrong here. i followed the dortania guide to the letter and everything else works perfectly.

I'm using it with Mojave and Clover (thunderbolt working). so far so good. No particular changes.
The board arrived yesterday and started up without any problems.
However, some of the USB ports don't work, so change kext.
We're also trying to launch Big Sur as Mojave will be out of support later this year. I can't do it well.
Thank you.

I don't use Big Sur but it works fine with Catalina and Clover.

I put kext, but I can't use some of it without any change.
The settings seem to be wrong, but I didn't understand.
I will continue to challenge.
Thank you.

An alternative (workaround) to this is Clover limit port patch plus USBInjectall KEXT...
