我的 Logitech Wave 无绳键盘将自己呈现为内核的两个设备。一个是常规键盘，工作正常，但所有附加键都显示为事件鼠标，这样
cat /dev/input/by-id/usb-Logitech_USB_Receiver-if01-event-mouse
按下按钮时会产生预期的垃圾，但 xev 根本不注册任何内容。我已经尝试过 hidpoint，它不想在 OpenSuse Tumbleweed 上运行，并且我已经尝试过
usbhid.quirks=0x46d:0xc517:0x40
使用内核参数来强制“多身份”识别，但目前我还无法理解，因此很可能无法正确识别明白我在做什么
关于如何最好地说服内核将额外设备识别为键盘而不是鼠标有什么建议吗？

我确实有一个 M570 轨迹球，接收器显然正在连接到它，尽管它已经通过通用接收器连接。
答案1
部分答案：如何获取更多信息
1）用 out 更新问题lsusb，以便我们可以看到供应商和设备 ID。
2）dmesg当组合被识别时，用输出更新问题。如果在启动消息中找不到加密狗，请拔下并重新插入加密狗以强制重新识别。
3)evtest在鼠标输入设备上以 root 身份运行，以查看 (a) 它声称会产生什么事件 (b) 当您按下其他键时它会产生什么实际事件。用该输出更新问题。
4) 查看驱动程序识别的/var/log/Xorg.0.log设备。evdev用相关行更新问题。
这至少应该可以查明设备被识别为鼠标的原因。
编辑
我不明白罗技的驱动程序是怎样的应该工作，但发生的情况是第二个设备似乎确实是为额外的钥匙保留的和对于鼠标 ( EV_REL) 事件，所以也许它是某种包罗万象的东西。
从内核方面来看，没有什么区别，内核只知道它将 USB HID 事件转换为输入事件。并udev使用误导性名称进行符号链接，但这也没关系。重要的是 X 似乎认为第二个输入设备是重复的（可能是因为它具有相同的名称）。所以我会尝试在其中xorg.conf包含一个InputClass部分，并尝试各种选项，希望让 X 接受该设备。我不知道为什么X拒绝了，所以我无法给出分步说明。如果描述不充分，请查看man xorg.conf的选项InputClass，并谷歌一下以了解它们的作用，有很多指南。
除了检查 X 日志之外，还要查看xinput列出的设备。即使它显示为鼠标，也足以使其显示在此列表中 - 您可以将其重新分配给Virtual core keyboard.还有它将要可能会被检测为鼠标，因为 X 认为（在大多数情况下可能是正确的）带有EV_REL事件的东西一定是鼠标，即使它有额外的EV_KEY按钮。
答案2
奇怪的是，将其识别为老鼠并不是最棘手的部分。这就是我在 xorg.con 中需要的全部内容
Section "InputClass"
Identifier "Wave keyboard extra keys"
MatchUSBID "046d:c517"
MatchIsPointer "on"
Driver "evdev"
Option "SendCoreEvents" "true"
Option "Buttons" "27"
Option "Device" "/dev/input/by-id/usb-Logitech_USB_Receiver-if01-event-mouse"
EndSection
问题是很多键发出的键码太高，xorg/evdev 听不到（扫描码> 255）我找到的解决方案是外路由器，使用此配置：
"Logitech USB Receiver" "/dev/input/by-id/usb-Logitech_USB_Receiver-if01-event-mouse" none key/418 "XKey/XF86RotateWindows"
"Logitech USB Receiver" "/dev/input/by-id/usb-Logitech_USB_Receiver-if01-event-mouse" none key/419 "XKey/XF86Game"
"Logitech USB Receiver" "/dev/input/by-id/usb-Logitech_USB_Receiver-if01-event-mouse" none key/421 "Xkey/XF86Launch7"
"Logitech USB Receiver" "/dev/input/by-id/usb-Logitech_USB_Receiver-if01-event-mouse" none key/423 "Xkey/XF86Launch8"
"Logitech USB Receiver" "/dev/input/by-id/usb-Logitech_USB_Receiver-if01-event-mouse" none key/397 "Xkey/XF86Launch9"
"Logitech USB Receiver" "/dev/input/by-id/usb-Logitech_USB_Receiver-if01-event-mouse" none key/430 "Xkey/XF86Messenger"
"Logitech USB Receiver" "/dev/input/by-id/usb-Logitech_USB_Receiver-if01-event-mouse" none key/136 "Xkey/XF86Search"
显然，每行末尾的 Xkey 映射可以根据需要进行调整。一把钥匙似乎无法映射 - 这是左上角的大银色钥匙，带有齿轮和窗口；这根本不会生成有意义的扫描码，所以我认为它不会起作用。那么，唯一的另一个问题是媒体中心和（相邻的）“音乐音符”键发出相同的扫描码，因此它们总是彼此重复并且看起来是相同的键。除此之外，所有 Fn 键和媒体键要么按预期工作，要么在短暂访问桌面键盘快捷键配置后工作。
