![Ubuntu 16.04 触摸屏问题](https://linux22.com/image/1062920/Ubuntu%2016.04%20%E8%A7%A6%E6%91%B8%E5%B1%8F%E9%97%AE%E9%A2%98.png)
我有一个带触摸屏的信息亭。它在 Windows 下运行良好,但在 Linux 下却无法运行。
dmesg 插入 USB 时显示

然后我使用 cat 来处理 /dev/hidraw1 我得到了一个输出事件然后触摸触摸屏
sudo cat /dev/hidraw1
但当我尝试 cat /dev/input/mouse0 或 /dev/input/event4 时,我什么也没得到,然后触摸屏幕。udevadm 输出
sudo udevadm info --attribute-walk /dev/input/mouse0
