if you are using the f20 bios, i think you need to edit one of the generate SSDT files. F20 bios handles the USB differently.

Most likely I am doing something wrong here, first time using MaciASL.
So I slid my USB-SSDT.aml file (which was copied on the desktop) onto MaciASL and I get this:
/*
* Intel ACPI Component Architecture
* AML/ASL+ Disassembler version 20160422-64(RM)
* Copyright (c) 2000 - 2016 Intel Corporation
*
* Disassembling to non-symbolic legacy ASL operators
*
* Disassembly of iASLpGWHg4.aml, Mon Feb 20 17:13:22 2017
*
* Original Table Header:
* Signature "SSDT"
* Length 0x00000071 (113)
* Revision 0x02
* Checksum 0xEE
* OEM ID "APPLE "
* OEM Table ID "Xhci"
* OEM Revision 0x00001000 (4096)
* Compiler ID "INTL"
* Compiler Version 0x20160422 (538313762)
*/
DefinitionBlock ("", "SSDT", 2, "APPLE ", "Xhci", 0x00001000)
{
External (HUBC, IntObj) // (from opcode)
External (UMAP, IntObj) // (from opcode)
Scope (\_SB)
{
Method (_INI, 0, NotSerialized) // _INI: Initialize
{
Store ("Method \\_SB._INI Called", Debug)
Store (0xCF30, \HUBC)
Store (0x013F, \UMAP)
}
}
}
Then I did the modifications inside the main window if that is correct:
/*

}
But I cannot save the file, getting errors. How should I proceed from here, should I edit in the main window or need to use compile or patch, just don't know the procedure after many attempts? Thanks for helping out.
