[solved] How to combine SSDTs?

[rich]

Apologies if covered already, I have tried searching this forum and googling and checking the MaciASL wiki.

How can I combine my Sierra USB fix and power management SSDTs?

Sierra USB fix SSDT:

DefinitionBlock ("", "SSDT", 2, "hack", "EC", 0x00000000)
{
    Device (_SB.EC)
    {
        Name (_HID, "EC000000")  // _HID: Hardware ID
    }
}

Start of power management SSDT (full attached):

DefinitionBlock ("", "SSDT", 1, "PmRef", "CpuPm", 0x00003000)
{
    External (_PR_.CPU0, DeviceObj)    // Warning: Unknown object
    External (_PR_.CPU1, DeviceObj)    // Warning: Unknown object
    External (_PR_.CPU2, DeviceObj)    // Warning: Unknown object
    External (_PR_.CPU3, DeviceObj)    // Warning: Unknown object
    External (_PR_.CPU4, DeviceObj)    // Warning: Unknown object
    External (_PR_.CPU5, DeviceObj)    // Warning: Unknown object
    External (_PR_.CPU6, DeviceObj)    // Warning: Unknown object
    External (_PR_.CPU7, DeviceObj)    // Warning: Unknown object

    Scope (\_PR.CPU0)
    {
        Name (PSS, Package (0x1F)
        {
            Package (0x06)
            {
                0x00000ED8, 
                0x000076C0, 
                0x0000000A, 
                0x0000000A, 
                0x00002600, 
                0x00002600
            }, 

            Package (0x06)
            {
                0x00000E74, 
                0x000073A0, 
                0x0000000A, 
                0x0000000A, 
                0x00002500, 
                0x00002500
            },
...

Here is what I have tried:

DefinitionBlock ("", "SSDT", 1, "PmRef", "CpuPm", 0x00003000)
{
    External (_PR_.CPU0, DeviceObj)    // (from opcode)
    External (_PR_.CPU1, DeviceObj)    // (from opcode)
    External (_PR_.CPU2, DeviceObj)    // (from opcode)
    External (_PR_.CPU3, DeviceObj)    // (from opcode)
    External (_PR_.CPU4, DeviceObj)    // (from opcode)
    External (_PR_.CPU5, DeviceObj)    // (from opcode)
    External (_PR_.CPU6, DeviceObj)    // (from opcode)
    External (_PR_.CPU7, DeviceObj)    // (from opcode)
    External (_SB_.EC__, DeviceObj)    // (from opcode)

    Scope (\_SB.EC)
    {
        Method (_DSM, 4, NotSerialized)  // _DSM: Device-Specific Method
        {
            Return (Package (0x01)
            {
                "EC000000"
            })
        }
    }

This does not work.

You don't need a SSDT for power management :

Oh! Looks like the below from your link answers this. I have a Haswell processor.

Which has better power management? I am guessing without SSDT as it has 30 total states, whereas with SSDT has 29 total states.

Thanks P1LGRIM just using the USB fix SSDT now and all is good.
