OK... Solution: Rename EC0 to EC (in my case).
Why: USB power, etc., must be critical to Catalina. I had EC0 in my ACPI segment and it was returning TRUE, so I had to use the rename facility in Clover (set that patch using Clover Configurator). No SSDT_EC.aml needed in this case.
For details, see this post. You will either need to rename EC0 (or H_EC), OR, use SSDT_EC.aml if neither EC0 or H_EC are present in IORegistryExplorer OR EC0 (or H_EC) _STA is set to FALSE (0).
To determine if _STA is set to TRUE, look for 0xfffffff as that is an unsigned INT for "true" (that part may not be clear to some people).
Once I renamed EC0 to EC, the installation took about 45 minutes to complete.
