Sleep/wake issues are often caused by misconfigured USB ports. However, on Catalina we'll run into boot issues on desktop systems if we don't have
EC and
USBX devices. If you look at the Designare Z390
Post-Install Files.zip in Post #1, you'll find a lot of files, among them are these two:
- SSDT-UIAC-DESIGNARE-Z390-V7.aml
- SSDT-EC.aml
The first file not only defines the USB ports, but it also creates a
USBX device that provides high electrical current to USB ports, which is necessary for charging big batteries (iPads for example). The second file creates an
EC device.
In your case, you may copy and paste the
USBX device from file #1 into your own USB SSDT. And you may simply copy
SSDT-EC.aml.
