Is USB injection/mapping needed with only 14 ports?

5 posts in this topic

Recommended Posts

Hey there,

 

I have a Z77X-UD5H board which has a total of 14 USB ports (counting USB3 as 2x ports). Is there still any need to use USBInjectAll.kext or to make a USB map? Running OpenCore with Lilu, VirtualSMC, WhateverGreen, AppleALC, AtherosE2200Ethernet, IntelMausiEthernet, RealtekRLT8111 kexts. Thanks

Z77 chipset, has 3 USB Controllers : XHCI + dual EHCI

 

XHCI [8086:1e31] - USB2/USB3 x4 : sub-total 8 ports
EHC1 [8086:1e26] - USB2 x8 : sub-total 8 Ports
EHC2 [8086:1e2d] - USB2 x6 : sub-total 6 Ports

 

Sum = XHCI (8) + EHC1 (8) + ECH2 (6) = 22 Ports

14 ports restriction is for one XHCI controller. Other controllers will be counted separately.
