“您没有使用 /dev/ttyACM1 设备的权限！”这是什么意思？

我一直试图通过 wammu 将我的 Nokia E65 手机连接到我的 Ubuntu 12.04。我尝试了“自动搜索手机”选项。但我在屏幕上收到如下错误消息：

Wammu is now searching for phone:

这是什么意思？如何解决此错误？

提前致谢。

答案1

这意味着您的用户没有权限访问 /dev（设备）。

尝试：sudo wammu

获取访问设备的权限

您可以做的另一件事是将您的用户放入蓝牙组系统中

答案2

在 ubuntu 12.04 中，所有串行设备都属于 dialout 组。您可以通过以下方式快速验证

ls -a /dev/ttyS*

你应该看到类似

crw-rw---- 1 root dialout 4, 64 May 30 18:22 /dev/ttyS0
crw-rw---- 1 root dialout 4, 65 May 30 18:22 /dev/ttyS1
crw-rw---- 1 root dialout 4, 74 May 30 18:22 /dev/ttyS10
crw-rw---- 1 root dialout 4, 75 May 30 18:22 /dev/ttyS11
crw-rw---- 1 root dialout 4, 76 May 30 18:22 /dev/ttyS12
crw-rw---- 1 root dialout 4, 77 May 30 18:22 /dev/ttyS13
crw-rw---- 1 root dialout 4, 78 May 30 18:22 /dev/ttyS14
crw-rw---- 1 root dialout 4, 79 May 30 18:22 /dev/ttyS15
crw-rw---- 1 root dialout 4, 80 May 30 18:22 /dev/ttyS16
crw-rw---- 1 root dialout 4, 81 May 30 18:22 /dev/ttyS17

假设你的用户名是，keith你可以通过执行以下命令将自己添加到该组

sudo adduser keith dialout

重新启动并重试。一切都应该正常工作。

答案3

将设备端口权限更改为：

chmod a+rw /dev/ttyXXX
