[Solved] Update 10.8.5 to Mav, lost USB 2.0

I updated from the latest ML to Mavericks and lost USB 2.0 functionality on the USB 3.0 ports. USB 3 sticks work fine.

This happened both after selecting the "USB 3.0" fix in PBI 6.1.9, and after reinstalling GenericUSBHCI.Kext (from Installer Backup, via Kext Wizard) and a new DSDT without this fix.

Tested with 2 Sticks of each kind.



EDIT: Re-installed GenericUSBXHCI.kext 1.2.6d2 from ML install and USB 2 and 3 both work again.

There's your mistake right there. The "Intel USB 3.0 patch" is only for use *without* GenericUSBXHCI.

Quoting from the description in the installer: "Select this, if you have Intel USB 3.0 controller on your board (the 4x40s models and all models with 7-series Intel USB3 controllers ). WARNING: This option will backup and then remove any version of GenericUSBXHCI.kext you may have!" There is a reason the installer removes the kext. And adding it back is not a good idea...

The idea is to use the patch instead of GenericUSBXHCI, such that you're using stock AppleUSBXHCI.

I had first selected the patch and changed nothing else. Then I noticed the nonworking usb2.
THEN I reinstalled that back-upped kext and generated a fresh DSDT without the patch.
After both ways failed I dug out the old version of the kext.
I'll try to reproduce.

EDIT: run PBI again for a fresh SDSDT with the patch; GenericUSBXHCI.kext was moved to Installer Backups ... and now it works -- oh the marvels of hackintoshing!

I think you meant DSDT...
