Ga-Z77-DS3H Mouse and keyboard not working in Mountain lion 10.8.0 - 10.8.3

FIXED! Ga-Z77-DS3H Mouse and keyboard not working in Mountain lion 10.8.0 - 10.8.3

Hello

I just finished building my first hackintosh! I installed Mountain lion 10.8 with Unibeast and Mountain lion from the app store, and everything went smooth! Until I rebooted After Installing 10.8.3 combo and Multibeast!
My system boots up nicely, but when I arrive at the screen where I have to write my apple ID I can't use my mouse and keyboard. but after waiting for like 10-15 min my mouse and keyboard work again! and this happens at every startup!! Btw the usb ports are working with everything else just not with my mouse and keyboard.
I think it's because of my Graphic card, cause when I boot with onboard graphics (Graphic card removed) this doesn't happen! I tried to re-install but nothing changed! btw i'm typing this from my hackintosh and everything works fine but I really dont want to wait 15 min every time before I can use my mouse and keyboard!!

Here are my specs:

Intel Core i3 3220 (with intel hd 2500)
Gigabyte GA-Z77-DS3H
MSI Geforce Gt210 1Gb
OZc 500W power suply
Geil 4GB Ram
MAC OS X Mountain Lion 10.8.3

Here are the option I checked with Multibeast 5.2.1:

User DSDT or DSDT-Free Installation
Audio > Realtek ALC8xx > Without DSDT > ALC887/88b > v100302 Current
Network > Atheros - Shailua's ALXEthernet v1.0.2
Bootloaders > Chimera v1.11.1 r1394

My system Definition is Mac Pro 3.1 (I also tried iMac 12.2)

Please help me!!

THanks.

NOTE: i'm using a USB mouse and keyboard!!!! and if I boot with -x my mouse and keyboard work but not my graphic card.

Please someone help me!! I really don't know what to do!

Do you have Legacy USB Support disabled in the BIOS ?

Which USB ports are your mouse and keyboard plugged into ?
I have the same board and mine are plugged into the ports above the PS/2 connector.

I have got the same problem with my GA-965P-S3 without DSDT and using a EasyBeast installation.

It wait for a few minutes and the mouse and keyboard will work.

I have search for a few post and they say we need a DSDT so solve the problem. However, my GA-965P-S3 do not have a DSDT in the database.
My mouse and keyboard was working on 10.8.1 but not working anymore after 10.8.2

I have USB legacy support enabled. I tried to change it to disable but nothing changed.

I tried every usb 2.0 and usb 3.0 ports but its all the same!! and again the usb ports are working but my mouse and keyboard are not.

This board does not have a DSDT.

Yes. I know. Your board is a 7 series board with UEFI which do not require a DSDT. However, if you try to make the DSDT by yourself, the problem may be solved mentioned by the others.

I found one similarity that causing the problem between your case and mine. We are both using GF210 as display.
I have heard that someone who got our problem with the same card got the problem solved after shifting to the built it HD4000 graphics.
However, in our case we cannot do so. Your HD2500 is not supported and my board do not have on board display.

Ye, I just build this hackintosh and my bank account is empty now but i'm saving for a EVGA GT640. I just bought the gt210 as a cheap replacement until I get the gt640. so I think the problem will be solved when I get the gt640.

But until then i'll look what I can do with that custom DSDT, and anyone got more options? maybe a kext for gt210??

I had the same issue randomly occurring after boot....maybe for a conflict between OS X and XHCI detection during boot ... after upgrading to 10.8.3 this strange behaviour has vanished...
