HID Support

HIDs (both via USB and via Bluetooth) are directly supported on Windows, MacOS, and UWP. On other platforms, HIDs may be supported but not delivered through HID-specific APIs (example: on Linux, gamepad and joystick HIDs are supported through SDL; other HIDs are not supported).

Every HID comes with a descriptor that describes the device. The descriptor of a HID can be browsed through from the input debugger by pressing the "HID Descriptor" button in the device debugger window.

HID Descriptor

HIDs are handled in one of two ways:

  1. The system has a known layout for the specific HID.
  2. A layout is auto-generated for the HID on the fly.

...

HID input is received as plain, unaltered HID input reports as received directly from the device or driver.

HID Output

Output reports can be sent to any HID by using the HIDO command. For an example, see DualShockHIDOutputReport.
