Ok!
This is a fresh built hackintoshi, with i5 4590, Asus b85m-plus mb, Rx460 and my old MBA 2012 ssd. The system was 10.14.2, preinstalled from the other well running hack, quite vanilla only efi clover.
The machine is running fine while first time boot. But into the desktop, I found all my USB2.0 connectors (both internal and external )had no function.
Back to win10, with the help of usbtree, I noticed all my USB2.0 connectors are under control of EHCI#2 (8086 8c2d) and nothing connected to EHCI#1. In mojave, the IORegistry showed both EH01, EH02, but only EH01 has connection and as expected everything connected to USB2.0 ports aren’t working.
Follow your instructions, I add USBInjectAll, ssdt_UIA(according to win 10), fakepciid, fakepciid_xhcimux, set usbowership, usb handoff, but nothing I can do to make ports under EH02 activated. Thanks for your help, quite long story.
In short, how to activate all my USB2.0 ports that under control of the EH02.
