Hi all!
Just upgraded my Yosemite (with Clover) installation using app, it went smooth, but afterwards I got only one USB port working. I can't even imagine where to look for solution to this, coz everything worked fine on Yosemite. Help me, please!
 
USB3 is not working for me. Maybe your non working USB ports are all USB3?
 
I'm on the same boat.

Clover 3229, P55 chipset, only one USB 2.0 port works on the entire machine. I have a 3.0 PCIe card that used GenericUSBXHCI but it's not loaded.

Also, rootless=0 gives me Kernel Panic.

Restoring my Yosemite backup.

Cheers!
 
Generic USB kext will KP in 10.11 this is a know fact for long time now, 10.11 has issues with USB on older hardware as well, also known fact. Only way to fix USB issues is DSDT patches and editing the USB kexts to match.

Newer hardware like haswell/broadwell work fine.

I didn't know about GenericUSBXHCI, but I do have my DSDT patched and works fine on Clover. I never needed any patched USB kext.

Can you be more specific about changes that needed in USB kexts?
