额外的键盘键（F13-F24+extras）在 Linux 下不起作用

Question

我正在尝试让 Linux 识别这个键盘上的一些奇怪的键（主要是在 KDE 中），它恰好是一台 Unicomp PC 122，带有额外的按键和一个自定义固件，它会根据https://www.usb.org/sites/default/files/hut1_2.pdf更高的 F 键音符。但是，在 evtest 或 showkeys 中，当我按下额外的键时，没有任何记录，它们也没有显示在 /dev/input 日志中。我知道它们存在的唯一原因是，当运行 usbhid-dump 时，它会显示按键及其特殊代码。现在，我还没有真正尝试过任何方法来解决这个问题，因为我不知道从哪里开始。最后，这是我按下所有特殊键（包括最后的非功能键）时 usbhid-dump 的转储。
