Hi! I trying many different kexts, but it does not working. I have mobo P7P55D-E with 2 USB 3.0. I using kext wizard and all kexts not working. Why ? Than i try command by terminal : sudo chmod -R 755 /System/Library/Extensions/PXHCD.kextsudo chown -R root:wheel /System/Library/Extensions/PXHCD.kext
sudo kextload -v /System/Library/Extensions/PXHCD.kext
sudo kextcache -m /System/Library/Caches/com.apple.kext.caches/Startup/Extensions.mkext /System/Library/Extensions

Terminal wrote:Requesting load of /System/Library/Extensions/PXHCD.kext.
/System/Library/Extensions/PXHCD.kext failed to load - (libkern/kext) different version/uuid already loaded; check the system/kernel logs for errors or try kextutil(8).
What does it mean ? Please, help!

I had the same problem with my board GA-Z87X-UD5H after updating.
Randomly some ports did work.

I d removed the kext and replaced it with the one provided in this thread.
2 ports on the back and all the ports on the front are working now stable.
But i have 4 more ports on the back wich dont do it at all.
is it possible to get them working or are these ports not compatible with OSX at all?
Does anybody know this?

Ok, so I have installed this USB 3.0 card:
orico pvu3-5o2u usb3.0

I have tried both rehabman and the 10.10 USB kexts. My system profiler recognizes my USB 3.0 card but it won't mount any of my harddrives. The USB 2.0 HDs I plug into the card light up but don't mount. My USB 3.0 hard drive light doesn't even come on. Any ideas?

I have the same mother board, EP45-UD3P. Just installed a PCIe 4 port USB card. Shows up in profiler, but Disks do not mount! it lights up USb2.0 flash drives, no light for USB 3.0 flash drives. Tried installing this driver http://www.sonnettech.com/support/kb/kb.php?cat=473&expand=_a3&action=b805. It got more info into the system profiler, but nothing else.

USB 3.0 Bus:


Host Controller Driver: AppleUSBXHCIPCI
PCI Device ID: 0x0014
PCI Revision ID: 0x0003
PCI Vendor ID: 0x1912

If anyone interested in...
I have Gigabyte H77-DS3H motherboard and after updating OS from Mavericks to Sierra and installing Clover in UEFI mode, my front panel USB stop working.
I've spend the half day trying to fix this sh*t :(
Then I've try to install Clover bootloader in Legacy mode instead UEFI and after that my front USB's started working!
