我刚买了联想 ThinkPad X201 t。我已经安装了 Debian Jessie（测试）。我能够使其所有硬件正常工作，但有一个例外。这就是移动宽带调制解调器。我已经检查过了：它在那里并且已正确插入。 BIOS 允许移动宽带。当我运行时lspci结果是：

好吧，没有一个看起来像它（至少对我来说）。如果不存在，是否意味着是硬件问题？因为我很确定它应该位于 PCI 总线上（而不是某些内部 USB 或其他总线）。
谢谢你！
答案1
该设备可能被 阻止rfkill。如果是这样，则这不是硬件问题。要进行检查，请运行 rfkill(1) 实用程序rfkill list。如果移动宽带调制解调器被列出并显示为“已阻止”，则使用相同的程序将其解锁。请参阅手册。
rfkill是一个用于激活和停用无线电收发器的子系统。当设备被 阻止时rfkill，它不会列在 PCI 探测中。
