USB Human Interface Device (full HID) support CONFIG_USB_HID Say Y here if you want full HID support to connect keyboards, mice, joysticks, graphic tablets, or any other HID based devices to your computer via USB. You also need to select HID Input layer support (below) if you want to use keyboards, mice, joysticks and the like.
You can't use this driver and the HIDBP (Boot Protocol) keyboard and mouse drivers at the same time. More information is available: <file:Documentation/input/input.txt>.
