Hi guys,

I followed Jake Lo's installation guide "Dell Latitude E6xxx/E7xxx Yosemite Install Guide".

 

Excellent guide, thank you Jake Lo.

 

USB 2.0 works (mouse and an USB 2.0 HDD) but no USB 3.0. Everithing else specified with the guide works flawlessly.

 

My Configuration:

 

Dell 7440, i7 4600 U, 8 GB Ram, 256 SSD, Yosemite 10.10.4.

 

Help please,

 

Kind Regards,

 

Maitrex

Hi Jake,

 

Thank you for your reply.

 

10.10.4 files have been already updated 2 days ago but I did it again  just to make sure that everything is all right.

I've also removed GenericUSBXHCI from System/Library/Extensions then I have restarted.

 

No change so fahr.

 

Any other sugestions?
