// both positional and descriptive information about the controller
|
|
// such as:
|
|
// - DIJOYSTATE2 for corresponding controller
|
|
// - XINPUT_STATE for corresponding controller
|
|
// - connection status (general or based on controller type or
|
|
// controller model)
|
|
// - XInput or DirectInput
|
|
// - friendly name
|
|
// - Vendor ID (VID)
|
|
// - Product ID (PID)
|
|
// - has force feedback/rumble or not
|
|
// - device handle
|
|
// - XInput ID
