Generally, the major number identifies the device driver and the minor number identifies a downlowd device possibly out of many that the driver controls: The ‘devfs’ approach is for the device driver to request creation and deletion donload ‘devfs’ entries related to the devices it enables and disables. Device nodes on Unix-like systems do not necessarily have to correspond to physical devices. Nodes that lack this correspondence form the group of pseudo-devices.
