我安装了 Ubuntu 20.04 LTS，但显然它无法读取 SD 卡，尽管我的笔记本电脑上有读卡器。我尝试运行它lsusb，它显示了读卡器，但sudo lsblk -f没有显示卡本身，显然sudo dmesg | tail -n 50初始化卡时存在问题，如果正确，如何解决？

答案1
在某些情况下，SDHC 和 SDXC 卡无法正确读取，但过去有几次我曾使用过一个小窍门。但问题是，这种解决方案通常会将复制速度限制为宣传传输速度的 1/8。因此，真正好的 SDXC 卡可能只能限制在 10MB/秒。
也就是说，如果你有兴趣，你可以尝试一下：
- 打开终端
- 创建文件：
sudo /etc/modprobe.d/sdcard.conf - 将其粘贴到文件中：
options sdhci debug_quirks2=0x2 - 保存文件
完成后，我们需要删除并探测一些模块：
sudo rmmod sdhci_acpi sdhci_pci sdhci
sudo modprobe sdhci; sudo modprobe sdhci_acpi; sudo modprobe sdhci_pci
然后，保存配置并使其处于活动状态：
sudo update-initramfs -u
多年来，我已经成功地在联想、戴尔和宏碁笔记本电脑上实现了这一点。唯一的问题是，正如我之前提到的，你无法获得 SD 卡的全部速度。
希望这也能帮助你
