我刚刚升级了操作系统，鼠标停止工作。它曾经适用于 openSUSE 42.1，但现在不适用于 42.3。如果我将其直接插入 USB2.0 连接，则一切正常，但集线器和交换机中的同一鼠标则不然。一切都通过“lsusb”枚举得很好。键盘、SD 卡读卡器和触控板工作正常。当切换到 OS/X 时，所有四个都工作正常。而且，如前所述，这一切都适用于 42.1。所以，它是内核软件。
我想知道如何调试它。消息“未指定输入驱动程序，忽略此设备。”让我停顿了一下，但它似乎继续加载“libinit”，并且该驱动程序发出令人欣慰的消息。注意：我使用了几种不同的 USB 鼠标，它们都直接插入端口即可工作，但通过集线器/交换机插入时则无法工作。我更喜欢办公桌上只有一只鼠标。 :)

在此期间，我移动鼠标并单击其按钮，但没有显示任何事件。 请注意：这在 openSUSE 42.1 上工作得很好，在 OS/X Sierra 上也工作得很好。确实如此不是使用 openSUSE 42.3。我不知道42.2。

# evtest /dev/input/mouse1 evtest: can't get version:
Inappropriate ioctl for device /dev/input/by-id
答案1
您可以从最低级别开始进行调试。您验证较低级别是否有效，然后查看较高级别。
原则上，集线器后面的鼠标应该可以开箱即用，因此我怀疑集线器存在硬件问题。
最低级别是USB：查看dmesg直接连接鼠标并在集线器后面时的输出（dmesg在之前和之后进行，额外的行是有趣的行，或者查看时间戳）。比较、查找错误，确保在两种情况下lsusb -v提供相同的信息。如果有必要，有一些工具可以在此级别上进行更多调试（如果确实发现集线器有故障）。用输出编辑问题dmesg不会有什么坏处。
下一级是内核输入系统：无论是端口后面的鼠标还是直接连接的鼠标，都evtest以root身份运行，选择设备，看看移动它是否会收到事件。如果集线器有缺陷，您可能无法在此处获取集线器后面的鼠标事件。
最后的级别是X。您已经查看了日志，它确实识别了鼠标，所以我认为问题不在于该级别。
编辑
usbmon如果在集线器后面移动鼠标时没有 USB 事件，而直接插入时有此类事件，则肯定是 USB 问题。
顺便说一句，event15如图event16所示来自其他鼠标（为什么你有两只鼠标？或者错误是否出现在假鼠标中？），你想要event2在给定的配置中，或者只是
evtest usb-Logitech_Gaming_Mouse_G400-event-mouse
但我期望 USB 事件具有与上述相同的行为（因为没有 USB 事件 -> 无输入事件）。
如果它与 openSUSE 42.1 一起工作，如果位于集线器后面（比较usbmon行为），请找到内核版本并向内核开发人员提交回归错误：https://bugzilla.kernel.org/
