SD 卡读卡器错误

Question

我在 Acer Aspire V5-571P 上运行 Ubuntu 16.10。我正在尝试使用内置读卡器读取微型 SD 卡（我知道它工作正常）。

Ubuntu 将无法识别该卡，我收到以下消息 dmesg

[11970.123839] mmc0: cannot verify signal voltage switch
[11970.259430] mmc0: tuning execution failed: -22

如果它可以帮助lsusb退货：

02:00.0是我的读卡器 如果我是对的。

总而言之，我认为 Ubuntu 知道那里有一个读卡器，但无法从中读取（没有驱动程序？），有人知道我必须做什么才能使其正常工作吗？

这听起来很疯狂，但假设您使用的是 microSD 到 SD 卡的适配器：尝试另一个适配器！我刚刚在使用已知良好的卡时遇到了这个问题，并发现它可以与不同的 SD 卡适配器完美配合。（“坏”适配器与不同的 microSD 卡一起正常工作。）我不知道为什么会这样，但在我的情况下这是一个一致的修复。
