New USB Raise Port Limit Patch for High Sierra

[raymondau]

Thanks.
8086:a36d is xHCI device-id. Same port layout as 200-series, 100-series.

Added support for 8086:a36d xHCI in USBInjectAll project (0.6.5).
Covered also in configuration guide:

Thanks so much. You are so efficient.

Thank you very much.
All the USB port works with the new kexts.

Thanks for testing.

Hi. On my Z370 motherboard the Device ID is a2af which is what's found in the 200-series injector. I think that the naming of the injectors may cause some confusion.

You can use whatever kext matches your device-id.
The README clearly mentions the device-id of each.

But was a big problem because no one USB works at the mac os installation stage ; no mouse&keyboard.

That is a new USB device with Intel B360 chipset ( I think that on H370, H310 too).
Intel Cannon Lake PCH USB 3.1 xHCI - device ID 8086_a36d
I replaced 8086_ a2af (200 series PCH USB 3.0 xHCI ) on 8086_a36d in both kexts
All USB ports are working now.
I create SSDT/USB on El Capitan MAC OS only . When Sierra/High Sierra arrive no need for me.
USB works very well on highspeed. Old rule ; new mac os new installation from beginning )

Note: Still no need to modify USBInjectAll.kext. You can provide whatever port data you want via SSDT.

Please attach ioreg and I'll add device id 0xa36d support to USBInjectAll.kext (and SSDT-UIAC-ALL) and add a XHCI-300-series-injector.kext.

Didn't he provide the ioreg file as needed? Im in a similar predicament. except my mobo is a h370.

Yes/support already added to USBInjectAll.kext.

The patch is used during port discovery only.
After you have a correct SSDT for USBInjectAll, and the number of ports injected are within the 15-port limit, no need for the patch.

I'm finally going to make the SSDT for the ITX Motherboard. I need clarification. On the GA-Z170N-WIFI, We have 4 usb 3.0 ports on the back, 1 usb-C 3.1 port. 2 usb 3.0 ports on the front from motherboard header, 1 m.2 wifi port (2.0) and 2 usb 2.0 ports from a motherboard header. With 2 ports defined per USB3.x, I count 14 ports for the USB3 and 3 ports for USB2. If I enable all the which is my desire, I'll have 17 ports defined in the SSDT. Will it work with the port limit patch implemented or do I have to start picking and choosing?

4xUSB3 back = 8 ports (HSxx + SSxx pair)
1xUSB-C (if it is on the xHCI not TB3): can be up to 3 ports (without switch: 2x SSxx, 1x HSxx), or 2 ports (with switch: SSxx+HSxx)
2xUSB3 front = 4 ports (HSxx + SSxx pair)
m.2 BT = 1
2x USB2 header = 2

Worst case:
8+3+4+1+2 = 18 (but may be only 17 depending on the type of USB-C)

It means you will need to sacrifice 2-3 to stay within the 15-port limit.

Thanks. That answers my next question. I have 15 ports to work with, not fewer than 15. The USB-C unfortunately isn't TB. I'll see what is in the IOReg output when I put a USB-C hub on it. I'll define at least 2 USB3 ports as SSxx only to hit 15. Maybe 3 if I need an extra for the USB-C. I want to leave the USB-C with full functionality.

Must test both orientations.

Omitting the HSxx will prevent USB2 devices from working in those ports; perhaps other problems.
