Ubuntu 16.04 触摸屏问题

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

[ 2548.828917] usb 1-1.4: USB disconnect, device number 5

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

有人能帮助它工作吗？
