Hi all! 
I´m new here and get my first experience with osx and hackintosh-systems. 
First of all... sorry about my bad english, i´m from Austria. 
  
My notebook: DELL Latitude E6220, with i5 CPU. 
What i have done: 
I installed El Capitan and I use the Clover-Bootloader. 
I copied all kexts that i´ve found in the forum for my model into Library/Extensions 
I copied the patched AppleHDA to System/Library/Ext.. too. 
I Installed the kext for Voodoo-Sound. 
After that, i repaired the kexts permissions and rebuild the cache. 
  
Everything works fine, except Wifi (because it is an Intel-based Card), and except the USB-Slots on the left and right side of the Laptop. The USB-Ports of the docking-station are functional. 
  
Before i installed the Voodoo-Sound kext, i was able to use all USB-Slots, unfortunately not afterwards.. 
  
Who can help? Is it possible to fix this problem? 
Thanks a lot! 
Greetings from Austria.
