USB 3.0 not working on Dell E6330, OS X 10.10.5

Aloha,

 

I have a nearly perfect, vanilla HackBook Pro thanks mainly to this site and this guide ...

 

https://osxlatitude.com/index.php?/topic/6372-dell-latitude-5x30-6x30-clover-install-guide/

 

However, one serious hurdle remains. This laptop will not recognize USB 3.0 drives reliably. It never sees them when first attached but sometimes after I sleep the unit and rewake it, they will then pop up along with a "not properly unmounted" message.

 

I ended up using the GenericUSBXHCI.kext along with FakePCIID + USBMux kexts to get this far but I think that even the developer of these kexts believes that they are not appropriate for this native Intel USB3 chip as the stock AppleXHCI will load if I remove the Generics. However, then the system freezes permanently when a USB 3.0 device is attached.

 

I should mention that USB 2. devices work just fine.

 

This is all running Yosemite 10.10.5 on a Dell Latitude E6330 with BIOS A11.  Heavy artefacts result with BIOS A12 and above on this one.

 

Anybody out there have one of these on 10.10.5 with solid USB 3.0 ?

 

Thanks in advance,

 

bisk
