Since this is the only place online I'm seeing it discussed so far...

AppleBusPowerController.kext has changed in Catalina, it no longer matches to EC. Here's a screenshot of the plists compared between Mojave (left) and Catalina (right).

Added in 53 minutes 40 seconds:

The upshot of this has been that I don't need EC or USBX to get USB power. I've added a section for AppleBusPowerController to the top of my SSDT-UIAC:


DefinitionBlock ("", "SSDT", 2, "hack", "_UIAC", 0)
       Name(_HID, "UIA00000")

       Name(RMCF, Package()
           "AppleBusPowerController", Package()


Works great, charges iPhone and iPad just fine and reports the extra current in system profiler. SSDT-EC and SSDT-USBX have been removed from my ACPI patches.
