I also did the USB port mapping in 10.14.4 with the Hackintool, and, after that, I said goodbye to the port limit patch. I went through 2 updates, 10.1.4.5 and 10.14.6, and my USB ports are still working fine.It took about 15 minutes to update my macOS to 10.14.6, and everything works well.

For this update I also took time to create my USBPorts.kext so I finally made all of my USB 3.2 Gen 1 ports work at 5 Gbps (theoretical).
