我正在尝试在 Linux (Ubuntu) 中连接秤(Dibal 系列 400),但无法成功。在安装驱动程序以启用虚拟 Com 端口后,秤可以在 Windows 上运行,但是当我在 Linux 中插入秤时,它会尝试启动,但过了一会儿秤会断电。

系统日志消息说:

作为附加信息,在 Windows 中它被识别为:

STMicroelectronics 虚拟 COM 端口 (COM3)它有下一个配置:波特率:9600奇偶性:无

当秤开始时(持续运行 3 或 4 秒),我测试过:

谁能帮帮我?

非常感谢,贾维。

最佳答案

终于解决了这个问题:

感谢那个链接:

https://github.com/dhylands/usb-ser-mon/blob/master/usb_ser_mon/mk-udev-rules-stm32.sh

用这个创建一个脚本并执行它。

#!/bin/sh
sudo sh -c 'cat > /etc/udev/rules.d/49-stm32.rules' <<EOF
