我正在尝试连接到 GPS 运动手表（类似于 Garmin 手表）。我运行的是 Ubuntu 12.04，64 位。理想情况下，我想将手表连接到其中一个 OS 运动软件，如 turtle sport 或 pytrainer。然而，目前我甚至无法访问设备本身保存的原始数据。
当我通过 USB 电缆插入手表时，它似乎被识别，因为它列在输出中
#lsusb

或者更详细

手表发出信号表明电池正在充电，因此它似乎从连接中获取了某种信号。
但是，我既无法访问该设备，它也没有出现在 nautilus 中。dmesg 的相关输出如下：

相应的驱动程序似乎已经加载：
#lsmod |grep cp210x
cp210x 21898 0
usbserial 47077 1 cp210x
似乎还创建了一个设备
#ls -l /dev/ttyUSB*
crw-rw---- 1 root dialout 188, 0 Dec 31 14:08 /dev/ttyUSB0
因此 - 就我的理解而言（可能真的不是很深入），它似乎可以正确加载和连接驱动程序。但是，在上面显示的 dmesg 输出之后，我看到了一些我不太理解的代码

从日志中我看到，该 GPS 设备没有提供可使用文件管理 ( nautilus) 安装和浏览的存储接口。
您必须使用专用工具通过串行接口从中读取数据/dev/ttyUSB0。尝试使用gpsbabel它支持多种协议的 GPS 数据收集设备。
Cygnal Integrated Products, Inc. CP210x只是 USB 串行转换器的型号和品牌。请参阅这里, 如何检查您的 GPS 设备。
