我在 SD 卡上设置了一台 16.04 服务器。我将 SD 卡放入 Transcend USB 3.0 读卡器。当我将读卡器插入物理服务器盒上的 USB 2.0 端口时，它工作正常。当我将其插入同一台服务器上的 USB 3.0 端口时，我收到大量错误，最终它会无限期挂起。
错误有几种不同的变化。

在很多地方都说“可能是 USB 电缆坏了？”我试过几种不同的读卡器。我知道它们都适用于 2.0，所以我怀疑这实际上是读卡器的问题。我也试过同一台服务器上的第二个 USB 3.0 端口，但问题相同。所以我怀疑这不是硬件问题，除非整个盒子都坏了。

事实证明 heynnema 是对的。我使用的主板的制造商在我发布此信息 5 个月后发布了 BIOS 更新。当我更新 BIOS 时，它运行正常。
