Support input device hot-plugging and removal via udev

[shengwen-tw]

udev is a device manager inside the Linux kernel that manages the hardware device files.

udev adopted an event-driven architecture that responds to kernel events, such as the addition or removal of hardware devices. When a device is connected or disconnected, the kernel generates an event, which udev processes to manage the corresponding device node.

By utilizing udev, we can support input device hot-plugging and removal.
