In 10.11+ Apple has changed significantly the way the USB drivers work. In the absense of a port injector, the drivers use ACPI to obtain information about which ports are active. Often, this information is wrong. Instead of correcting the DSDT, a port injector can be used (just as Apple did for their own computers). But in order to create such an injector, you must first determine which ports are actually being used. And to do that you need to inject all ports so you can test all ports on the computer to determine which ones correspond to each available port address. You can't test a port that is disabled...
That's where this kext comes in.
This kext attempts to inject all ports for each controller, and for hubs as well. You can use this kext (temporarily) to enable all ports so you can determine which ports really need to be in the final injector. Only the (potential) hub on EH01.PRT1 and EH02.PRT1 are injected. Other hubs would require modifications. So far, I haven't seen internal hubs connected to other ports. The kext automatically determines the ports (and their addresses) based on the specifc USB controller chipsets.
This kext is only for 10.11+. It has no use with prior versions.
Currently, only Intel controllers are supported. The most commonly used SMBIOS model identifiers are in the kext.
It is not intendended that this kext be used long term. It is best to create a custom injector containing only the ports that are active on the target machine.
For some chipsets, you may need to bypass the 15-port limit in 10.11. In particular, XHCI controllers with device-id that starts with '8' will need the patch to bypass the limit. The patch was created by arix98 and published on insanelymac.com here: http://www.tonymacx86.com/el-capitan-laptop-support/173616-guide-10-11-usb-changes-solutions.html
How to Install
Install the kext with your favorite kext installer, such as Kext Wizard.
Or install via Terminal: sudo cp -R Release/USBInjectAll.kext /Library/Extensions sudo touch /System/Library/Extensions && sudo kextcache -u /
If you have a 9-series chipset XHC controller, 8086:8cb1, install XHCI-9-series.kext from the project as well. The USB3 drivers will not load without this injector kext. Update: As of 10.11.1, this injector is no longer needed as direct support was added. If you need it, go back in history: https://github.com/RehabMan/OS-X ... 7db10cf48500333a7bd
Note: This kext assumes you already renamed EHC1->EH01 and EHC2->EH02. It also assumes your XHCI controller is named XHC (not renamed to XHC1). These names EH01/EH02/XHC are best to avoid conflicts with built-in port injectors for Apple computers. Refer to config_patches.plist in this repo for the patches required (config_patches.plist/ACPI/DSDT/Patches).
Build Environment
My build environment is currently Xcode 7.0, using SDK 10.11, targeting OS X 10.11.
Keep in mind the Info.plist is generated by generate_Info_plist.sh. Do not edit the Info.plist directly. USBInectAll_template-Info.plist serves as the starter Info.plist, with each model injected using USBInjectAll_model_template.plist. This allows new models to be added easily by modifying the script.
