steam无法正确识别Python虚拟设备

Question

我正试图在Linux（特别是Manjaro）上创建一个虚拟操纵杆设备，用于steam游戏。我在这个项目中使用Python，并尝试了evdev和uinput库，结果是相同的：系统似乎可以识别设备（/dev/input/files正确创建，evdev和jscal都正确工作，等等），但steam不接受它作为有效的控制器。 这是我用来测试它的代码：

#!/bin/python

import uinput
import time

def main():
    events = (
        uinput.BTN_JOYSTICK,
        uinput.ABS_X + (0, 255, 0, 0),
        uinput.ABS_Y + (0, 255, 0, 0),
        )

    with uinput.Device(events) as device:
        for i in range(20):
            device.emit(uinput.ABS_X, 5, syn=False)
            device.emit(uinput.ABS_Y, 5)
            time.sleep(2)
        device.emit_click(uinput.BTN_JOYSTICK)

if __name__ == "__main__":
    main()

在控制台中运行steam，当连接物理控制器时，我得到以下输出：

但是，当我创建虚拟设备时，我会得到以下输出：

Local Device Found
  type: 0001 0001
  path: sdl://2
  serial_number:  - 0
  Manufacturer: 
  Product:      python-uinput

  serial_number:  - 0

  Interface:    -1

因此steam似乎正确地检测到了该设备，但没有将其识别为有效的游戏控制器。我尝试更改设备的所有详细信息（名称、类型、产品等），以匹配现有的物理设备，但运气不佳。它确实为虚拟设备输出了两次“找到的本地设备”，而为物理设备只输出了一次，我不确定这是否相关，或者是什么原因造成的

提前谢谢
