我无法访问使用 Transystem iBlue 747 收集的跟踪数据。设备已打开，可能已被识别（ubuntu 16.04）。据报道，它在 ubuntu 下运行良好。

我尝试使用 mtkbabel 下载曲目但被问及设备是否已打开。
mtkbabel /dev/ttyACM0 -f test -c
Cannot open /dev/ttyUSB0. Did you switch ON the GPS device?
bt747 和 gpsd 也没有成功。
任何提示都非常感谢。抱歉我的技能有限。如果我们可以避免使用 Windows，我会非常高兴，因为我最近在大学工作站上安装了 Linux。谢谢，詹斯

已解决。感谢用户 march！！
通过将自己添加到 dialout 组可以永久解决 /dev/ttyACM0 的权限问题。您必须先注销然后重新登录，然后才能识别组更改。
如果 terrik 是您的用户名，您可以使用 sudo usermod -a -G dialout terrik 执行此操作。
