The port limit patches should be used in line with the fully implemented XHC USB kexts.

However, it is still recommended to disable the port limit patches and use truncated 15-port kexts instead. This might avoid buffer overruns and will make your system more vanilla with respect to future macOS updates.
Enjoy and have fun,
