So my iPAD not charging over USB under power problem continues: From my IOREG I can see that the XHCI driver and DSDT edits are correctly loading, In system information I can see this:

As you can see all devices are connected to the main bus via what is shown as 2 Renesas hubs. These shows up in IOREG as IOUSB:/HubDevice@14900000 and IOUSB:/HubDevice@14a00000 which are connected to XHCI Root Hub USB 2.0 Simulation @ 14. (Please note I don't have an external hub this is how the ports of the motherboard are showing)

 

DSDT edits showing up on XHCI root:

Not so on hub device:

I've tried adding the current-available DSM DSDT edits to the HUB that is in the DSDT under _SB.PCI0/XHCI/RHUB but with no success. I've tried numerous Clover settings, and BIOS settings. Any one have any ideas?

 

Darwin Dump IOREG DSDT and Clover stuff attached.

Nothing is wrong with graphics, it just isn't using custom boot screen, I removed that message so it's not misleading.I can't fix your issue with memory without full boot.logs.........................................

Thanks for answer!!

Set Smbios->Trust=true

 

Thanks Slice.  I already had Trust=true.  But you pointed me in the direction of SMBIOS and that's where the solution lied.  I have details about my memory in my SMBIOS but I added that it was single channel and that there were 2 slots and that fixed it.  The option to include that info must be pretty new.  I never noticed it before.

I am not sure if XHCI driver has a charge function.

 

So I set BIOS to

 

XHCI Mode: Enabled

XHCI hand off - Disabled

EHCI hand off - Disabled

Then plugged a USB 3 front port into the other internal USB 3 header port plugged in a iPad and hey presto it charges.

As you can see apart from this sole USB port ALL the USB functionality on the Z87X UD5 TH is provided via 2 x Renesas uP720210 Hub chips. These are not passing the extra current that Clover/DSDT specifies. Least we now know what is going on.

Let work with you. I have no experience with Clarksfield.

First question. Why you set this?

4:735  0:000  Config set EnableC7: -
4:735  0:000  Config set EnableC6: +
4:735  0:000  Config set EnableC4: -
4:735  0:000  Config set EnableC2: -
4:735  0:000  Config set C3Latency: 999

Are you sure your chipset/CPU supports C6?

Reduce latency to 0xFA=250

 

Did it ever works with other Clover revision or with other bootloader or with other OSX version?

May be Yosemite is not supporting PM with MacBookAir5,2? Can you give me 

/System/Library/Extensions/IOPlatformPluginFamily.kext/Contents/PlugIns/ACPI_SMC_PlatformPlugin.kext/Contents/Resources/MacBookAir5_2.plist

to study? I have no Yosemite.

 

  • No i am not sure that my chipset/CPU supports C6 !
  • Speedstep works now when the machine wake from sleep, Very strange !!
  • there is no MacBookAir5,2 in this folder, i attached the kext so you can take a look IOPlatformPluginFamily.kext 5.8.0.zip

Spotlight indexing is one of the things that makes it useful and powerful and normally it should not be disabled. That said we don't really need indexing of an ESP. The correct thing to do is have .metadata_never_index file in ESP. This should be included in Clover installers imho but can also be added later by a user.

A little question.

 

Is it possible to have a Windows program that would allow to select the Startup Disk like BootCamp Control Panel does ?

 

I'm able to do it from OS X but not from Windows.

 

Thanks !
