我该如何解决这个问题……？ :/
答案1
如何排除故障哪一个您的笔记本电脑有哪个问题？您的问题标题中只提到了“读卡器”，没有提到其他内容。Thinkpad W520 列出了以下外围设备：
4-in-1 Media Card Reader slot
One ExpressCard slot
One SmartCard slot
你写了关于“lsusb”但是仅有的与智能卡读卡器（从信用卡和同类卡上的芯片读取数据）相关。
使用智能卡读卡器需要特定的软件，而且 GNU/Linux 只支持某些类型的智能卡。列出块设备让我非常怀疑您实际上并不是在谈论智能卡读卡器，而更可能对 4 合 1 媒体读卡器感兴趣（这涉及 SD 卡及其同类）。
然而，关于该读者的信息只会使用
串行通信
或类似设备，因为至少内部读取器通常不是通过 USB 连接，而是通过 PCI 快速通道连接。
那么您实际上想要使用哪种阅读器和哪种媒体来做什么，以及哪些症状让您认为出了问题？
