我正在尝试构建一个arcade machine使用Beaglebone Black GPIO开关的Happs controller set. 我构建了一个python script在启动时运行并将所有 GPIO 正确分配给Advmenu and Advmame. 该脚本在命令行上运行良好，但我无法uinput在里面工作Advmenu or Advmame。我已尝试对udev规则进行多次更改，但均未成功。目前似乎SDL1.2是已安装的SDL版本，但目前我正在构建最新的SDL2.

udev 文件 /etc/udev/rules.d/40-uinput.rules

SUBSYSTEM=="input", KERNEL=="uinput", MODE="0666", GROUP="uinput", ATTRS{name}=="arcade", ENV{ID_INPUT_KEYBOARD}="1"

这是我创建并一直在使用的程序

任何想法为什么虚拟键盘不起作用？
