created an SSDT for Clover for my USB ports which appeared to have initially caused the problem back in Mojave. That resolved it until 10.15.4.
Everything worked except USB ports needed to be configured and sleep still not working. To accomplish that I found the following How to which explains in depth the how and why it works “How-to: USB mapping for OpenCore https://aplus.rs/2020/usb-mapping-how/”
I choose to use the SSDT and SSDT-EC-USBX rather than the kext it creates as well as I felt it would be cleaner. After adding that to my config.plist and EFI folder and rebooted all worked perfectly.
first, i am on mojave. is your SDDT and SSDT-EC-USBX for mojave ? or not ?
thanks to explain (limitations, configuration to share USB2/USB3)
i agree, i think the USB-C on this CM is that element may caused the problem, with clover.
Again could you uplord your EFI ?
thanks a lot
