USB Driver Changed Again - PB6

[RehabMan]

After reading through majority of the thread, it seems like my problems closely mirror Matt's. I applied the Windows 8 SSDT patch (at least I think I did, I put it in /EFI/CLOVER/ACPI/patched), which is what fixed Matt's problem with the FakePCIID_XHCIMux kext not recognizing USB3 devices correctly from what I understood. No luck on my system. I used the same bios settings as Matt (smart auto, and enabled both handoffs) as well. It's a possibility I still need a port injector kext but I kind of gave up on that as I couldn't figure out how the port numbering worked.

The SSDT has no effect without the associated DSDT patch in config.plist/ACPI/DSDT/Patches.

@lunaoso I'm sure you can use ioreg to find your port numbers, I did. Trying to remember were it was.

I'm not really sure how but I got it to work with the SSDT, FakePCIID_XHCIMux kext, and the last DSDT edit you posted. I'm still not sure if my SSDT is loading or not because I've never used one before, but I mean it works so I guess I call that a success!

Bad idea to use a DSDT from another computer. It works with that DSDT because that DSDT was extracted with 'patchmatic -extract' run when the config.plist patches were in place (result is a patched DSDT that has _OSI changed to XOSI).

I'm sorry I should've explained that better. I used my DSDT, but I made the last edit that you suggested (changing the if statement to always true for the Windows thing (post #199)). I'm still no expert on DSDTs or SSDTs or any of that stuff, but I definitely learned a lot over the past day just messing around with stuff and thanks to you.

OK... good...

Still note that the SSDT has no effect without the associated patches for _OSI->XOSI.

You should be able to eliminate the SSDT for the same result.

Ok cool. I'll try that.

EDIT: As expected, it works fine without the SSDT.

It is probably something your DSDT is doing in _WAK or _PTS when Windows 8 ("Windows 2012") is detected.

The only way to deal with it is by starting to more selectively patching DSDT. For example, you might disable the _OSI->XOSI patch, then make sure XSEL is called in some other way.

For example, in _OSC, you can force XSEL to be called like this:

            Method (_OSC, 4, Serialized)  // _OSC: Operating System Capabilities
            {
                Store (Arg3, Local0)
                CreateDWordField (Local0, Zero, CDW1)
                CreateDWordField (Local0, 0x04, CDW2)
                CreateDWordField (Local0, 0x08, CDW3)
                If (^XHC.CUID (Arg0))
                {
                    Return (^XHC.POSC (Arg1, Arg2, Arg3))
                }
                Else
                {
                    //was: If (LGreaterEqual (OSYS, 0x07DC))
[B]                    if (1)[/B]
                    {
                        If (LEqual (XCNT, Zero))
                        {
                            ^XHC.XSEL ()
                            Increment (XCNT)
                        }
                    }
                }

                If (LEqual (Arg0, GUID))
                {
                    Store (CDW2, SUPP)
                    Store (CDW3, CTRL)
                    If (LEqual (NEXP, Zero))
                    {
                        And (CTRL, 0xFFFFFFF8, CTRL)
                    }

                    If (NEXP)
                    {
                        If (Not (And (CDW1, One)))
                        {
                            If (And (CTRL, One))
                            {
                                NHPG ()
                            }

                            If (And (CTRL, 0x04))
                            {
                                NPME ()
                            }
                        }
                    }

                    If (LNotEqual (Arg1, One))
                    {
                        Or (CDW1, 0x08, CDW1)
                    }

                    If (LNotEqual (CDW3, CTRL))
                    {
                        Or (CDW1, 0x10, CDW1)
                    }

                    Store (CTRL, CDW3)
                    Store (CTRL, OSCC)
                    Return (Local0)
                }
                Else
                {
                    Or (CDW1, 0x04, CDW1)
                    Return (Local0)
                }
            }

That will allow XSEL to be called as if _OSI returned true for "Windows 2012", but the DSDT won't do other things differently as it relates to Windows version.

Been playing around with this, like said I've never patched a dsdt before, how exactly do i do it?

I tried once and it wouldn't save due to compile errors.

Ive attached my clean dsdt just incase your feeling really kind .....

Fixing errors... DSDT patches from here (read the README for proper MaciASL setup): https://github.com/RehabMan/Laptop-DSDT-Patch

Apply: "Fix ADBG Error"
Apply: "Fix PARSEOP_ZERO Error"

Compile. Should compile without errors.

Now you can make the changes to _OSC.

 

[matt77303]

Any chance you could do it.

Least then I no I'm trying something I no is right.

If you see what I mean.
