Hello ,

according to your tutorial, i had been set "XHCIportLimit " value to "false" in config.plist, then use Hackintool app to remap usb port under catalina macos for my laptop ,this tools export two files with “aml ” name extension and one file "usbports.kext". then i add this two files ("SSDT-UIAC.aml and SSDT-EC-USBX.aml") into ACPI folder,

and i add relevant parameter uid_exclude=HS05.....etc in config.plist .

Finally ,i use this boot usb to install big sur , laptop don't show interface with prohibition icon again, but screen always show below interface .

Attachment is pictures which is always stay in interface and Photo which is unfold EFI file structure view .

u have a ec device injected by ssdt?

[kai wang]

hello,

About the method for "a ec device injected by ssdt", i use Hackintool tools to remaped usb ports ,this tools will export SSDT-EC-USBX.aml and SSDT-UIAC.aml this two files , then i put above this two files into ACPI folder ,finally i use propertree tools to add this two records in config.plist . this method is right ,isn't it ?

if this method isn't right ,please tell me how to add a ec device injected by ssdt for laptop .
