XID Overview

XIDs are USB devices.


USB Adapters

The Xbox input devices are USB devices. As such, you can connect a keyboard to the Xbox, or a gamepad to your PC. In fact, Linux already has drivers for the gamepad. In order to preserve Xbox hardware, please do not cut OEM Xbox cables to make an adapter. Decent adapters can be acquired cheaply (~$10 USD ea. on 2017.04.30).

Port (From) Plug (To) Link
Xbox USB-A Amazon

Wiring

Untested / unverified! Take this with a grain of salt.

Pin Typical cable color Description
1 Green USB D-
2 White USB D+
3 Black GND
4 Red VCC
5 Yellow VBlank signal from video output (for Lightguns)

Protocol

Controller to Xbox

typedef struct XIDGamepadReport {
    uint8_t bReportId;
    uint8_t bLength;
    <Data>
}

Xbox to Controller

typedef struct XIDGamepadOutputReport {
    uint8_t report_id; //FIXME: is this correct?
    uint8_t length;
    <Data>
}


Standard Gamepads

USB Descriptors

Most standard gamepads share the same USB descriptor. Usually the only difference will be the VID / PID. See https://github.com/xboxdrv/xboxdrv/blob/stable/src/xpad_device.cpp for a list of devices.
