Using udev
DEVICE JUNGLE
Learn how to create your own udev rules and deploy command-line tools to monitor and control udev events to clear your way through the Linux device jungle.
In the past few years, Linux has progressed in the field of hardware detection and management. The days of static device files huddled below the /dev directory are long gone, and Devfs is also obsolete. Since kernel 2.6, udev has been responsible for handling both the device filesystem and Hotplug, which includes setting up the required device files, setting permissions, and optionally launching certain programs.
