[Guide] Native USB Fix for Desktops - No Injector/Kext Required - SkyLake+

[MaLd0n]

--About Credits for this method--

The source for the methods is the motherboard ACPI is not mald, geng, etc. Is just duplicated one OEM method(GUPC in this case), renamed(We need device name) and applyed connectors type(Credits is not for us. We just renamed and duplicated devices) . All credits for it is for Piker Alpha HERE and not for Italian people. This method of mapping has existed for many, many years and is not our credit.  

The resume is: We stole method GUPC from intel and apply the Piker way ofc.?

1- Check OEM SSDT about USBs, in my case is SSDT-6-A M I.aml, i'm using a Z390 mobo

2- Create Methods into SSDT OEM inside Scope _SB.PCI0.XHC.RHUB, Internal and USB 2 is native, just create USB 3, USB-C

-In some cases some ports have a Method _STA = Zero, change to 0x0F to enable

We just need duplicate Methods (GUPC for example) native from our ACPI table and Inject values

Connector types in the ACPI specification(pages 524 and 525)

https://uefi.org/sites/default/files/resources/ACPI_6.0.pdf

0xFF - internal - GUPC

Zero - USB 2 - TUPC

0x03 - USB 3 - MALD

0x09 - USB-C - MAL0 (Same HSxx/SSxx in both orientations, then it has an internal switch)

0x0A - USB-C - MAL1 (Different HSxx/SSxx in each orientation, then it has no switch)

 

-Example

GUPC and TUPC is a native Methods

 

Quote

Method (GUPC, 1, Serialized)

{

Name (PCKG, Package (0x04)

{

Zero,

0xFF,

Zero,

Zero

})

PCKG [Zero] = Arg0

Return (PCKG) /* \_SB_.PCI0.XHC_.RHUB.GUPC.PCKG */

}

 

Method (TUPC, 1, Serialized)

{

Name (PCKG, Package (0x04)

{

One,

Zero,

Zero,

Zero

})

PCKG [Zero] = Arg0

Return (PCKG) /* \_SB_.PCI0.XHC_.RHUB.TUPC.PCKG */

}

 

Method (MALD, 1, Serialized)

{

Name (PCKG, Package (0x04)

{

Zero,

0x03,

Zero,

Zero

})

PCKG [Zero] = Arg0

Return (PCKG) /* \_SB_.PCI0.XHC_.RHUB.MALD.PCKG */

}

 

Method (MAL0, 1, Serialized)

{

Name (PCKG, Package (0x04)

{

Zero,

0x09,

Zero,

Zero

})

PCKG [Zero] = Arg0

Return (PCKG) /* \_SB_.PCI0.XHC_.RHUB.MAL0.PCKG */

}

 

Method (MAL1, 1, Serialized)

{

Name (PCKG, Package (0x04)

{

Zero,

0x0A,

Zero,

Zero

})

PCKG [Zero] = Arg0

Return (PCKG) /* \_SB_.PCI0.XHC_.RHUB.MAL1.PCKG */

}

}

 

3- Enable or Disable USB ports

-Check example TUPC

Look at Method _UPC - USB Port Capabilities

Enable = One

Disable = Zero

Example

Quote

Scope (\_SB.PCI0.XHC.RHUB.HS01)

{

Method (_UPC, 0, NotSerialized) // _UPC: USB Port Capabilities

{

If ((H1TC == Zero))

{

If (((UMAP & One) == One))

{

Return (TUPC (One))

}

Else

{

Return (GUPC (Zero))

}

}

Else

{

Return (\_SB.UBTC.RUCC (H1CR, One))

}

}

 

If you need identify your USB ports like USB-C for example, change TUPC/GUPC to MAL0

 

Quote

Scope (\_SB.PCI0.XHC.RHUB.SS01)

{

Method (_UPC, 0, NotSerialized) // _UPC: USB Port Capabilities

{

If ((H1TC == Zero))

{

If (((UMAP & One) == One))

{

Return (MAL0 (One))

}

Else

{

Return (GUPC (Zero))

}

}

Else

{

Return (\_SB.UBTC.RUCC (H1CR, One))

}

}

 

0xFF - internal - GUPC

Zero - USB 2 - TUPC

0x03 - USB 3 - MALD

0x09 - USB-C - MAL0 (Same HSxx/SSxx in both orientations, then it has an internal switch)

0x0A - USB-C - MAL1 (Different HSxx/SSxx in each orientation, then it has no switch)

 

-USB 2 PORTS inside USB 3 BUS, just Inject USB 3

Excellent guide [ref]MaLd0n[/ref], awesome!!

Bit by bit we will understanding more about ACPI patching, thank you.

But one doubt, I need to keep the USB Injection at Clover? E.g: Devices > USB > Inject/FixOwnership/HighCurrent

Thanks

[MaLd0n]

[ref]Allan[/ref], u can use it in clover without problem

@MaLd0n,

I was waiting a long time for something like this.

Unfortunately I didn't manage to create a correct one.

If you have the time , can you help me out ?

I'm attaching my native acpi ssdt for usb and my current usb configuration.

Thank you in advance.

SSDT-2-xh_OEMBD.aml.zip

the image have all ur real ports?

[mathewgx]

Working great !!!

Just had to change a port from usb3 to usb2 but that's nothing.

Thank you , again , my friend.

Hi, guys

ffor which version of macOS is this method applicable?

Thanks everyone

Hey, thanks for the guide but it seems I didn't grasp it right.

Do you mind looking at what I did wrong?

Also, can I also remove XHCI-unsupported.kext if I use this method?

[ref]piyushrawal[/ref], dont need usbinjectall and XHCI-unsupported.kext

use ssdt with usb patch limit and u don't need more

SSDT-xh.aml.zip

https://Olarila.com/forum/viewtopic.php?f=62&t=6539

if u need change connectors, check inside all _upc and change

0xFF - internal - GUPC

Zero - USB 2 - TUPC

0x03 - USB 3 - MALD

0x09 - USB-C - MAL0

0x0A - USB-C - MAL1

btw, SSDT-xh is a native name or u renamed it? use a native name and clover replace a correct table, i never test with rename

It's working with limit patch. But I am unable to disable USB ports to get it under 15 limit by setting Return (MALD (One)) to Return (MALD (Zero)). It has no effect.

And yes, renaming was a bad idea. It doesn't work if renamed.

[MaLd0n]

[ref]piyushrawal[/ref], remove ssdt uiac

It's deleted. If you wish to take a look, I've attached the clover folder. It contains stock ssdt in origin folder as well.

I am sorry for being a total noob.

And thanks a ton for your help.

Got it! Thanks a lot.

For laptops (at least for my skylake laptop), it is also worth to know that native _UPC or _PLD is within DSDT itself. Similarly, like how Maldon had described all we need to do is replace zero to one and define usb type in the scope of UUPC and UPLD as per my example.

Hope this helps for some of us.

_UPC or _PLD is within DSDT
