如何知道哪个/ dev / input / eventX（X = 0..7）有Linux输入流？ [英] How can I know which of the /dev/input/eventX (X=0..7) have the Linux input stream?

问题描述

我正在尝试捕获linux键盘/鼠标输入，我正在从 / dev / input / event2 中读取事件。但是似乎输入有时被指向 / dev / input / event2 ，有时到 / dev / input / event3 。我想知道是否有一个地方我可以找出哪个流有输入？

解决方案

只是偶然发现 - 相当晚的一天。

您可以使用以下方式找出不同设备的名称和其他属性：

  cat / proc / bus / input / devices 
  

I am trying to capture linux keyboard/mouse input, and I am reading events from like /dev/input/event2. But it seems the input are sometimes directed to /dev/input/event2, sometimes to /dev/input/event3. I wonder if there is a place I can find out which of the stream has the input?

解决方案

Just stumbled across this -- rather late in the day.

You can find out the names and other attributes of different devices using:

cat /proc/bus/input/devices
