Update!!

Use https://github.com/USBToolBox/tool instead to get the mapping

Refer to https://dortania.github.io/OpenCore-Post-Install/usb/#macos-and-the-15-port-limit

So the process of USB mapping is defining your ports to macOS and telling it what kind they are, the reasons we want to do this are:

  • macOS is very bad at guessing what kind of ports you have
  • Some ports may run below their rated speed(3.1 ports running at 2.0)
  • Some ports may outright not work
  • Bluetooth not working
  • Certain services like Handoff may not work correctly
  • Sleep may break
  • Broken Hot-Plug
  • Even data corruption from XhciPortLimit

打开Hackintool，可以看到有多少个USB Controllers

Lets open our previously downloaded IORegistryExplorer.app (opens new window)and search for our USB controller(s).

Three USB controllers

  • XHC0@60000000
  • XHC1@20000000
  • XHC0@61000000

Pay attention that they’re individual controllers, as this means each USB controller has it’s own port limit. So you’re not as starved for USB ports as you may think.

Finding which ports match with which controller

    • PRT3@60300000
    • PRT4@60400000
    • PRT5@60500000
