我正在尝试使用名为 sakis3g 的脚本让 3G USB 适配器在运行 Raspbian Wheezy 的 Raspberry Pi 上工作。
然而，在尝试执行此操作时，我不断遇到问题：当尝试连接到 USB 设备时，脚本会打印“非法指令”并且不再继续。我已经发布了一个关于 Raspberry Pi Stack Overflow 网站上的问题，并给出了尝试遵循的指南（BigCowPi 的回答）。然而，正如我在那里所说的，当我尝试运行lsusb（该指南中的第一件事）时，它仍然输出“非法指令”并且不再进一步。
我尝试过重新安装乌斯布蒂尔斯和libsub-1.0-0对于armhf，但这并没有帮助解决问题。
还值得一提的是，我目前无法访问互联网，因此我一直在下载安装包并使用 dpkg，而不是像 apt-get 这样更简单的东西。
我还没有从 Raspberry Pi 网站上得到答案，所以我认为可能值得在这里询问，因为无论如何这可能是一个与 Linux 更相关的问题。
