我买了一个与旧键盘类似的新键盘。旧的可以用，新的不行。新键盘有一个不寻常的 HID 描述符并发送一个额外的数据字节。有没有支持这种键盘（描述符）的Linux驱动程序？
通过 的通信日志cat /sys/kernel/debug/usb/usbmon/3u，仅字节序列（按 A，释放 A；按 Shift，按 A，释放 A，释放 Shift 序列）：
不工作的 9 字节键盘通信：
00000400 00000000 71
00000000 00000000 71
02000000 00000000 71
02000400 00000000 71
02000000 00000000 71
00000000 00000000 71
旧键盘通信工作：
00000400 00000000
00000000 00000000
02000000 00000000
02000400 00000000
02000000 00000000
00000000 00000000
奖励：额外的字节是什么？ （我总是0x71在那里看到。）
新键盘的 HID 描述符通过cat /sys/kernel/debug/hid/<interface>/rdesc：

（遇到的问题联想专业无线键盘， 一个华硕键盘... 两款无线键盘均由致伸科技制造。）
（Windows 和 GRUB 上未遇到此问题。）
（伊夫·特鲁多已经尝试过并实施了司机它忽略了额外的字节，但我宁愿使用普通内核中的一些东西和一些不那么hacky的东西。）

它既包含Input字段（来自键盘的报告）又包含Output字段（发送到键盘的控制消息），并且它们混杂在一起，这并不奇怪。输入字段也非常标准：第一个字节具有用于修饰键的位（左移和右移/ctrl/alt/meta），后面跟着一个常量零字节，然后是最多 6 个同时按下的键的 6 个字节。正如您从报告示例中看到的，这也正是键盘发送的内容。
最后一个额外字节的范围为 -128 到 127（71-15 也是如此），并被描述为“通用桌面”，使用索引为 0x168。公开的 HID 使用表 (HUT) 版本 1.12 中未分配此索引，因此我不知道它的含义。它必须是某种模拟范围（键盘倾斜？压力？其他传感器？）。它是什么也不是特别重要，它只会被 HID 转换层忽略。
输出消息也是标准的：1个字节，其中3位控制键盘LED（num lock、caps lock、scroll lock），5位未使用。
Usage Page (Keyboard)然而，从输出字段到下一个输入字段的切换Usage Page (LED)发生在块的中间，显然这混淆了内核 HID 描述符解析器，因此它也将此输入字段解释为“LED”，这是没有意义的根本没有，并阻止它按应有的方式翻译按键。
这是一个错误：要么在内核 HID 描述符解析器中，要么在 HID 描述符中。在第一种情况下，它应该被修复，在最后一种情况下，描述符应该在内核中得到一个怪癖，以便它可以被修复。无论如何，将其作为错误报告给内核维护人员。
一旦修复，内核应该可以正常识别键盘事件。不需要额外的驱动程序（尽管在错误修复之前使用一个驱动程序作为解决方法并没有什么坏处）。
内核 HID 解析器位于 中drivers/hid/hid-core.c，以防您想自行修复它。
答案2
正确的修复已合并到 Linux 内核中：https://lkml.org/lkml/2019/3/27/350
只要 5.2 版本发布，它就会可用，并且可能会在某些发行版上向后移植。
答案3
只是为了增加 @jan-molnar 解决 HID 解析的努力，我的键盘具有非常相似的 rdesc，因为它也是由 Primax USB 芯片（PiD 4e63）驱动：

我问这里
不要以为伊夫·特鲁多的“司机”就是答案。我愿意帮忙。
答案4
这终于解决了！我在Ubuntu 18.04内核：4.15.0-64，Ubuntu 18.04.3内核：5.0.0-29中测试它。
键盘和鼠标似乎工作正常，没有任何问题！我必须禁用用于使其工作的解决方法！https://github.com/y-trudeau/linux_lenovo_ultraslim_plus
根据此报告，Fedora 30 中也修复了该问题：https://bugzilla.redhat.com/show_bug.cgi?id=1625415
