我尝试在 Fedora 28 上访问 SD 卡，但没有成功。系统信息如下：

$ lsb_release -a
LSB Version:    :core-4.1-amd64:core-4.1-noarch:cxx-4.1-amd64:cxx-4.1-noarch:desktop-4.1-amd64:desktop-4.1-noarch:languages-4.1-amd64:languages-4.1-noarch:printing-4.1-amd64:printing-4.1-noarch
Distributor ID: Fedora
Description:    Fedora release 28 (Twenty Eight)
Release:    28
Codename:   TwentyEight

我无法使用两个不同的读卡器访问不同的 SD 卡。尽管可以在 macOS 和 Windows 上访问，但它们都不会显示在 Nautilus 文件浏览器、桌面或其他明显的地方。

系统根据输出识别读卡器lsusb：

然后我在插入和拔出卡时查看了 udev 事件：

$ udevadm monitor
monitor will print the received events for:
UDEV - the event which udev sends out after rule processing
KERNEL - the kernel uevent

KERNEL[701.434565] change   /devices/pci0000:00/0000:00:1d.7/usb1/1-3/1-3:1.0/host4/target4:0:0/4:0:0:2/block/sde (block)

此外，我还查看了内核消息：

$ dmesg
[  603.846840] usb-storage 1-3:1.0: USB Mass Storage device detected
[  603.847749] scsi host4: usb-storage 1-3:1.0

[  639.490479] sd 4:0:0:0: [sdc] Attached SCSI removable disk

dmesg和的输出都udevadm monitor表明该卡应显示为sde。不过，fdisk -l并没有列出sde。除此之外，尝试手动安装设备会引发错误：

$ mount -t auto /dev/sde /mnt/
mount: /mnt: no medium found on /dev/sde.

我不确定所需的驱动程序模块是否已正确加载，因为输出mmc0中没有 -like 条目dmesg（正如我从基于 Debian 的系统中了解到的那样）。也不lsmod列出mmc0内核模块：

$ lsmod | grep mm
rtl8192c_common        61440  1 rtl8192cu
rtlwifi                98304  3 rtl8192c_common,rtl_usb,rtl8192cu

唯一mmc似乎可用但未加载的类似模​​块是mmc_block和mmc_core：

$ modprobe mm  # listing suggestions using tab auto-completion
mma7660    mmc_block  mmc_core   mms114

我怎样才能解决这个问题或者至少缩小范围？

答案1

尝试mount这样做还为时过早。此消息表明检测到硬件：

[  629.830776] sd 4:0:0:2: [sde] Attached SCSI removable disk

但是除非设备上有可挂载的文件系统，否则您无法挂载该设备。使用lsblk或blkid查看系统是否可以识别 SD 设备。

以下是输出的样子以供参考：

LSBLK 
$ lsblk

最后建议您可以尝试安装/重新安装udisks2.这在标题为 AU Q&A 中进行了描述：Ubuntu 16.04 未检测到 sd 读卡器，但我过去在 Fedora/CentOS 上也遇到过这个问题。

$ sudo yum reinstall udisks2

-or-

$ sudo dnf reinstall udisks2

答案2

总而言之两个都我测试过的读卡器有故障。不过，请参考这个答案如果您可以消除与硬件相关的问题。
