Question

当我连接调制解调器befour PC启动一切正常。但是当连接到工作PC时有bug。

没有使用来自其他地方的任何驱动程序都在默认的debian jessie存储库上工作。

这里是dmesg：

找到this article：

在良好的序列中，cdc_ether首先被加载并声明为设备。新eth1接口已配置完毕且一切正常。后做了一些研究，我决定放手一搏。如果我们这样做会怎样残疾的司机？它似乎是最新的Sierra Wireless 设备并不真正需要该驱动程序，因为它可以通过USB进行通信 CDC。它有什么害处？我没想到，所以我打开了 /etc/modeprobe.d/blacklist.conf（不要忘记使用vi调用sudo！）然后去上班这是我在底部添加的内容。
