GA-Z77X-UP5-TH + ML 10.8.4 - wont stay ASLEEP, wake reason: ECH1??

[Pr3fix]

Hey there,

I can't get my install to stay asleep. It will go to sleep for 2-3 seconds before waking up at the lock screen. The wake log gives reason as "ECH1".

Hardware:

Z77X-UP5-TH
Corsair DDR3 1600 (XMP Profile 1)
i7-3770k
AMD 7950 gpu

THINGS I HAVE TRIED:

* disabled Internal CPU PLL Overvoltage
* removed AppleIntelCPUPowerManagement.kext
* removed GenericUSBXHCI.kext (accidentally installed, believe it is not needed for this board)
* installed nullAppleIntelCPUPowerManagement.kext to negate the other one
* set hibernate mode to 2 with "sudo pmset -a hibernatemode 2"
* disabled Wake On LAN in BIOS
* disabled Wake On Thunderbolt in BIOS



This is driving me crazy. How do I fix sleep? Why does my build keep waking when others dont?

I have discovered the solution to the sleep issue.

The cooler I use, the Corsair h100i, is an all in one liquid cooler that connects to the motherboard internal usb2 header. I completely had forgotten about that - I was getting ECH1 wake reason because ECH1 = USB2 header, and the cooler is connected to the internal USB2 header. Apparrently Corsair coolers don't play nice with OSX and it was causing the wake issue.

I too have a Corsair H100i cooler connected to the internal USB header of my mATX build and am also getting ECH1 wakes.

You state that you have a solution. What is it, please?
Or, is it that you just know the reason... the cooler.

Well, I disconnected the USB link. It is not needed except to use Corsair Link software, which is, of course, Windows only...
Double checking temps with Temperature Monitor shows that the CPU is cooled just as it was with the USB link connected.

Testing showed the continuance of immediate wake after sleep, but Console showed the cause to have changed to EHC2.
I changed the port connecting my Aten KVMP and the spontaneous EHC wakes ceased.

Anyhow, my mATX build now sleeps and wakes as it should.

Thanks Pr3Fix and rockyroad. I also have a Corsair water cooler that was connected to an internal USB header. For months, I had not been able to use Sleep, because it would immediately wake back up.

Thanks to your tips, sleep is working normally now, after disconnecting the water cooler from USB.

Woohoo!
