how to find keyboard in /dev on osx

Question

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? Thanks.

Edit: 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.

OS X uses its own system to manage the PNP device tree, see http://developer.apple.com/mac/library/navigation/index.html?section=Topics&topic=Drivers%2C%20Kernel%2C%20%26amp%3B%20Hardware&kind=topic to get started
