我正在尝试在 Linux 下使用游戏手柄（内核是 4.16.10），但似乎没有从中得到任何输入事件。
该设备是一个假冒的 Xbox 360 控制器，似乎已被检测到，dmesg报告如下：

但是，我无法获取任何输入事件，无论是使用jstestnor evtest（无论是作为 root 还是非 root）。xboxdrv顺便说一句也是如此。
usbmon仅在插入和拔出控制器时获取数据。按下按钮时不会报告任何内容。
但evdev检测到几个可能发生的事件：

附赠 Wireshark 的 usbmon 报告和带有 Windows 对应部分的 csv： https://filebin.net/n416mszk1155zbjb （抱歉，txt 版本尚未消化）
有谁有任何想法或线索来找到解决这个问题的方法吗？
谢谢，
答案1
如果按下按钮时没有收到任何 USB 流量，则表示硬件上的某些部件工作不正常。
要么是硬件损坏了，要么是它需要在宣布自己为的阶段进行正确的初始化SHANWAN PS3/PC，或者可能是在化身中，因为Microsoft X-Box 360 pad它需要 Windows 驱动程序的初始化命令，而 Linux 驱动程序不提供该命令。
下一步是将它连接到具有正确 Windows 驱动程序的计算机，看看它是否在那里工作。如果不行，请返回它；如果是，请嗅探 USB 流量（有适用于此的 Windows 工具，谷歌搜索）以找出应如何初始化它。

我仍然不明白这两个设备之间为什么会出现这种混乱（而且也没有时间详细研究）。但是，我们可以看到，在 Windows 下，在发送关键事件之前，会发生以下交换：
In: 01 03 02
Out: 01 03 02
In: 02 03 00
Out:
In: 03 03 03
Out:
In: 08 03 00
Out:
在 Linux 下，只显示第一行；永远没有答案。这可能是缺少初始化（或其他原因）。
在查看时，我发现这xpad是将 HID 事件转换为输入事件的内核驱动程序，我无法从您的dmesg摘录中看到它是否已加载。在双重检查中，使用 进行检查lsmod。（不过，我在快速检查源代码时找不到这些序列）。
似乎还有一个用户空间库，参见例如这里，它似乎比内核驱动程序工作得更好，所以这也值得一试。
答案2
我有同样的问题，但我设法识别了 Windows 驱动程序的初始化序列，并在此基础上编写了一个将必要的代码发送到设备的 Python 脚本。
这是脚本，您必须使用 sudo 运行它：pyusb-测试.py
