El capitan USB issues - possible fix.

Status
Not open for further replies.
I followed the steps carefully in the post #1, but I still don't have my USB3 port recognised by El Capitan.

I have a Gigabyte H81M-HD3 board, the back USB2 ports and the pin USB2 headers are working, but my USB3 ports aren't. Also, if I set XHCI -> Smart Auto, my USB DAC stops working in the back USB2 port. Only working if I set XHCI -> Auto. :think:

Using iMac 14,1 sys. definition, already tried removing port restrictions under:
System/Library/Extensions/IOUSBHostFamily.kext/Contents/PlugIns/AppleUSBXHCIPCI.kext/Contents/Info.plist
And tied with/without EHC1, EHC2 patch:

Seems like the fix is not working for VIA USB3...
Can someone help me? What extra info do I need to attach?
Thanks in advance! ;)

I wouldn't use somebody else's dsdt, they can be different even with the same motherboard.

As far as i understand this fix inly works with the Intel USB 3.0 controller not with VIA ports...Check if your motherboard had Intel USB3 ports in addition to the VIA ports. Those should work in theory?
