Gigabyte H470M USB 2.0 port mapping 11.7.2

[billdlv81]

I'm having problems trying to map the USB 2.0 ports on this install.

I'm using Open Core 0.8.8. I tried installing the USBInjectAll kext, several versions including 0.7.3 and 0.7.5 and enabling the XhciPortLimit quirk using OCAuxillaryTools. Hackintool shows only 12 ports, 6 USB 2.0 and 6 USB 3.0. Only the XHC controller shows up. None of the USB 2.0 only ports show up or work at all. There are 2 of those on the MB back panel and 2 are on the front panel of my case connected to the MB jumper.

I read in the MB FAQ that if you disable USB 2.0 support in BIOS then you are limited to 12 ports total. But I don't see that option in this BIOS to enable or disable. Legacy USB support is enabled, XHCI Hand-off is enabled (I tried disabled), USB Mass Storage Driver Support is enabled. I also tried using the #2 USB header on the MB for the front panel.

I checked the ports using Linux mint and all of them work.

As for the config.plist I'm using the stock one for iMac20,1. The only thing I had to add was framebuffer /connector data in PciRoot(0x0)/Pci(0x2,0x0).

I was able to figure it out.

I had to use USBMap (USBMap) instead of the USBInjectAll. I then used hackintool to check my work.

All the ports on my setup work now. All the USB 3.0 can do 2.0 as well.

Well done.

Out of interest, let me give you a bit more info should you need it in future.

The Intel H470 chipset has 14x available physical USB ports - 8x USB3.2 and 6x USB2-only. So as the USB3.2 ports can also act as USB2 too, that makes a total number of USB ports 22x. However, in your case Gigabyte appears to have only activated 6x USB3.2 ports, one of which is USB-C, making the total 18x.

In your USBMap.kext the USB ports which are physically USB3.2 - i.e blue - should be set to UsbConnector type "3", even for their HS** personalities - except for the USB-C port which is 9 or 10 and you've done that. You should only use "0" for the black or Internal USB2-only ports. This is because we are configuring the number of contacts within the plug, with this variable.

USBInjectAll will only work to open-up all the available physical and virtual ports if it is a version written for the system-definition you are using - iMac20,1 in this case. Then, depending on which version of macOs you are using, may or may not need the XhciPortLimit quirk to be set in the config.plist.
