## What it is
A Python script for macOS that discovers and maps USB ports on a system, working around macOS's 15-port-per-controller limit. It generates a custom injector kext so all physical USB ports function at their correct speeds.

## Use cases
- map usb ports on hackintosh
- fix usb 3 ports only running at usb 2 speeds in macos
- create custom usb injector kext without USBInjectAll
- work around macos 15 port limit
- generate USBMap.kext for my motherboard
- rename xhci controller via acpi for usb mapping

## When to choose
- you're building or maintaining a Hackintosh and need all USB ports working
- you want a USBInjectAll-free, system-specific USB mapping kext
- you need to map XHCI, EHCI, OHCI, or UHCI controllers including AMD chipsets

## When to avoid
- you're on Linux or Windows - the mapping process runs in macOS
- you need USB mapping for a real Mac, which typically doesn't require it
- you want an automated one-click solution - the process requires manually plugging devices into every port
