我已经安装了 Redhat（未购买）6.1（新 Redhat），我正在尝试在其中连接 Idea-3g NetSetter。我已经通过 Yum 安装了 ppp 和 wvdial 并在 /etc/wvdial.conf 文件中进行了必要的更改，但我无法配置它。
当我浏览日志时，我发现我的系统正在将此设备作为大规模存储设备而不是将其作为调制解调器设备。我去了谷歌，但它也没有帮助我
在 Wvdial.conf 文件中，我必须输入 /dev/ttyUSB0 但在 dev 目录下没有像 ttyUSB 这样的文件。有 tty1，tty2 等。所以我该如何解决这个问题。请帮助我..一些必要的信息在这里

请帮助我如何解决它
我正在提供 wvdial coomand 的输出，它一次又一次地重新启动并显示 ppd 错误 16。我试图找出它并发现这个错误是调制解调器挂起的。我尝试了很多，但问题就是这样。
