Just installed the patched PXHCD.kext on my 2008 MacBook pro, works fine with my AKE USB 3.0 Express Card, speed is great. (Chose this one because it perfectly fits into the macbook so the card can stay in it all the time)
But: My MBP doesn´t sleep anymore when I had an USB3 device connected. Just gets stuck with a black screen and running fans. Even removing the Express Card doesn´t help, the macbook won´t sleep, no matter what I do.
Already tried to unload the kext before sleeping, but then I´ll get this:
sudo kextunload /System/Library/Extensions/PXHCD.kext
(kernel) Can't unload kext com.LaCie.driver.PXHCD; classes have instances:
(kernel) Kext com.LaCie.driver.PXHCD class PXHCD has 1 instance.
Failed to unload com.LaCie.driver.PXHCD - (libkern/kext) kext is in use or retained (cannot unload).
Anyone got an idea? I wont need USB3 daily, so it would be okay to restart my macbook every time I used USB3, but of course it would be much better to have it running completely stable.
thanks in advance
EDIT: Hm, after a reboot kextunload is working properly... Okay, then I´ll do this everytime I have used USB3...
