At its core, a HID is any device that takes input from humans or provides output to them. Because they follow a standardized specification, most operating systems (Windows, macOS, Linux) have "inbox" drivers that recognize them automatically the moment they are plugged in. Input: Keyboards, mice, game controllers, and touchscreens. hid device

Because modern operating systems like Windows, macOS, and Linux have a built-in "HID Class Driver," they can read these descriptors and start working instantly without needing a CD or a manual download. 3. The Shift to Wireless and Web The Human Interface Device (HID) class specification allows
