Okay, so I figured out how Zenith432 patched AppleUSBXHCI.kext in hex code:

75 5B-->EB 5B
66 3D 00 01-->66 3D 00 00
74 A1-->EB A1
F6 00 02 74 40-->F6 00 02 EB 40   (This one is actually "74 40-->EB 40", but you'll find two "74 40".)


Here is the patched kext from 10.8.3 Build 12D44.
USB 3.0 patch (10.8.3 Build 12D44).zip


Don't know why my system became very LAG when using this patched kext.  Could someone give it a try?

IIRC, same was happened in my system with PXHCD. Meanwhile, CalDigit gives disk ejection error but continues working after 10-15 seconds.


Hi, would you mind sharing the original kext from 10.8.3. I would give it a test. Not worth to get the whole image since it's beta

Hello guys, the Mountain lion is quite slow to shut down and restart.
Activating the verboose I found the problem that I enclose in the picture, how do I fix?

Thank you all!
