Mac OS X 相当于“udevadm info -a -n /dev/ttyACM0”

Question

Mac OS X 中与 Linux 命令等效的命令是什么udevadm info /dev/ttyACM0？

/dev/tty.whatever我正在尝试在脚本中获取有关 TTY 设备 ( ) 的 USB 信息。

更新：我正在寻找有关 TTY/串行端口设备（不是磁盘）的信息。这是我正在寻找的输出类型（关键字段已突出显示）：

我真的很感兴趣将DEVNAME( /dev/ttyACM3) 与VENDOR和MODEL信息相匹配。

我认为这就是您正在寻找的：

将 rj45 串行电缆插入我的OSX 10.14.6 Mojave Macbook 的USB-C 端口的样本反馈如下：

我知道这是 4 年前发布的，但注意到没有人回答。嘿，迟到总比不到好！HTH-
