Every time a change happens within the device structure, the kernel emits a uevent which gets picked up by the device manager. The device manager then follows the rules declared in the, and  directories. Based on the information contained within the uevent, it finds the rule or rules it needs to trigger and performs the required actions. These actions may involve the creation or deletion of device files, and may also trigger the loading of particular firmware files into kernel memory.
