udev is a Device manager

udev is a generic kernel device manager. It runs as a daemon on a


Linux system and listens to uevents the kernel sends out (via netlink

socket) if a new device is initialized or a device is removed from the

system. The system provides a set of rules that match against exported

values of the event and properties of the discovered device. A

matching rule will possibly name and create a device node and run

configured programs to set-up and configure the device.
