SD 卡显示在 dmesg、lsusb 和 lswh 中，但不显示在 lsblk 或 fdisk 中

最近，我的 Android 设备无法检测到我的 SD 卡，因此我将其连接到我的 PC（运行 Kubuntu）以找出问题所在。结果如下：

dmesg正确检测到读卡器和连接的大容量存储设备，并在/dev/sda、/dev/sdb、/dev/sdc和中显示 SCSI 磁盘/dev/sdd。我不知道为什么它出现在所有四个中。stat将它们的大小显示为 0。mount所有这些都失败，表示未找到介质。

lsusb正确检测设备：

Bus 001 Device 016: ID 0dda:2026 Integrated Circuit Solution, Inc. USB2.0 Card Reader

lswh -class disk检测到四个磁盘，就像dmesg：

既不lsblk提供fdisk与 SD 卡或任何/dev/sd*文件相关的任何输出。

这是完整的dmesg输出：
