R – how to find keyboard in /dev on osx


On linux / ubuntu, the keyboard and mouse devices are found
in /dev/input/by-path/
Where is the keyboard device mounted in osx?
I added a usb keyboard, and no devices got added in /dev folder.
Is it located somewhere else, or is it totally unaccessible?

I was able to get some info on the keyboard using libusb:
046d:c315 (bus 26, device 3)
and usb prober in developer tools from apple…
however none of them mention a /dev special file or another way to access it.
