Running Mojave 10.14.6, and using the -xcpm boot arg, and having an IcyDock USB 3.1 Gen2 Type C hub plugged into the Gen2 type C port on the Z370 mobo, with 2 USB Type A sticks and one SSD using type C cable plugged into it (as a test), the system crashes immediately after booting into Mojave (Finder?) so not possible to shut down or effectively force quit apps as it is slow and doesn't help. I do not have a custom DSDT yet. I have all the relevant port limit patches for Mojave and Catalina.
Previously the both Gen2 ports stopped working properly and I reflashed the BIOS and it improved things a lot. I have tried fewer devices and one or two at at time in the Gen2 type A and C slots and it is more stable. Everything shows ok however in Clover and is detected ok if I boot up into Linux. It is 100% stable if I plug in multiple drives into the 3.1 Gen1 ports. Even when it is not crashing, when using one SSD plugged into the Gen2 port, and it is detected, it generally slows the whole machine down and half the time there is a connection issue whereby OS X cannot read to the file system of the drive towards the end of the back up. It used to work normally a year ago but running the system with those EFI back ups doesn't help.
Should I be using the genericusbxhci.kext? Or doing something else? TIA.
Edit: I have installed the kext and it seems superficially to be working as smoothly as a baby's bottom.
