My boot and system log is flooded with this looping exception and attempted recovery, it happens repeatedly:

I found a similar thread located here: https://www.tonymacx86.com/threads/usb3-xhci-problems.235265/ but I didn't want to highjack the thread with my own problem. The advice in the thread by @VioletDragon was to "delete ports", can anyone elaborate as to how I would go about doing that?

I thought maybe it's helpful to include full clover folder. Am i even using correct system definition for my hardware? iMac18,3 ?

Additionally I have added the contents of my /Library/Extensions

@RehabMan since you seem to know a lot about usb maybe you can help me?

Since my original post I have learned how to disable ports and have disabled as many as possible. This is the current config i have. also attached is my ioreg.
