我刚刚安装了 Ubuntu 20.04。如果使用 SD 卡适配器，则无法访问任何 SD 卡。我尝试了多个适配器，并在其他计算机上进行了相同的测试。SD 卡或适配器在其他系统上运行良好，但在我的系统上却无法识别它。
如果我使用 USB 适配器，我就能访问 SD 卡。
这绝对不是硬件问题，因为如果我在计算机上打开 Windows 分区，我就能访问它。
这是可用磁盘列表的屏幕截图，其中 SD 卡已通过 SD 卡适配器插入：
这是一个简单的存储设备，如果我在 Windows 分区上打开它，它很容易打开，但在 Ubuntu 上。
一些论坛建议我重新安装 udisks2，我照做了，但问题并没有解决。
sudo apt-get install --reinstall udisks2
我该如何解决 ？
硬件信息：

编辑：正如评论中所建议的，我使用 GParted 来获取更详细的信息，这是启动 GParted 后的结果：
编辑2：我运行了命令lspci，然后lspci -v | grep -iA15 sd得到了以下输出：

答案1
我是 Unix 新手，但我使用了上面列出的命令（lsusb、lsblk、DISKS），这些命令确认闪存卡确实被笔记本电脑看到。唯一的问题是 FILES 看不到它，即使它已格式化。DISKS 注意到闪存卡上没有分区，所以我让它创建一个（确定整个（16 GB）将是一个分区）。这解决了问题，FILES 现在可以访问它了。它就像任何驱动器或 USB 棒一样。
