ttyACM0 在一段时间后停止流式传输

我有一个 arduino 设备，可以读取光传感器，然后结果可以通过其 USB 端口传输。在 Windows 上，使用名为的软件，Serial Osciloscope我可以读取设备发送的数据。但是当我运行

sudo cat /dev/ttyACM0

显示一些数据（约 450 行）后它保持停止状态。

请帮助我，任何帮助都将非常感谢。

提前致谢。

PS：这是命令的输出

通过从以下链接添加 udev 规则来解决https://www.pjrc.com/teensy/49-teensy.rules

ATTRS{idVendor}=="16c0", ATTRS{idProduct}=="04[789B]?", ENV{ID_MM_DEVICE_IGNORE}="1"
ATTRS{idVendor}=="16c0", ATTRS{idProduct}=="04[789A]?", ENV{MTP_NO_PROBE}="1"
SUBSYSTEMS=="usb", ATTRS{idVendor}=="16c0", ATTRS{idProduct}=="04[789ABCD]?", MODE:="0666"
KERNEL=="ttyACM*", ATTRS{idVendor}=="16c0", ATTRS{idProduct}=="04[789B]?", MODE:="0666"

另存为/etc/udev/rules.d/49-teensy.rules
