Fixing USB

What this SSDT does

So on 400 series motherboards, certain OEMs have broken the ACPI spec and this results in issues when booting into macOS. To fix this, we have a few ways to fix it:

  • Turn off the RHUB and force macOS to rebuild the port
    • Quick and dirty, not recommended long term
  • Fix the bad ACPI table
    • Proper fix
