This document introduces how to configure attributions of device files under /dev directory via udev.
There are no static files under /dev directory for devices, devices are created/removed dynamically by udev(or udevd) which is a daemon monitors what devices are connected/disconnected on to the kernel, and run additional appropriate scripts at the time. Manually creating files under /dev directory or changing its file attributions does no effect, manually modifications would be ignored or could be revised automatically.
