问题描述
我最近升级到 ubuntu 16.04，但我的 SD 卡读卡器无法工作。系统根本不检测阅读器。 lsusb 的输出信息量相当少：
lsusb
Bus 001 Device 002: ID 8087:8000 Intel Corp.
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 003 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 002 Device 005: ID 8087:07dc Intel Corp.
Bus 002 Device 004: ID 0bda:572a Realtek Semiconductor Corp.
Bus 002 Device 003: ID 046d:c245 Logitech, Inc. G400 Optical Mouse
Bus 002 Device 002: ID 04f3:024c Elan Microelectronics Corp.
Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
所以我什至不知道我的 SD 卡读卡器型号是什么。我用的是ideapad u430。

最佳思路
可能是一个 installation-issue 可以用 re-installation 解析？！这将涉及包 udisks2 。
-
重新安装软件包
udisks2\n
sudo apt-get install --reinstall udisks2\n -
重新启动机器
\n
systemctl reboot\n
SD 卡插入后应该能够被识别(小心插入、拔出和插入)。
次佳思路
如果您安装了读卡器，lsusb 应该会给您类似的信息：
Bus 001 Device 005: ID 0bda:0129 Realtek Semiconductor Corp. RTS5129 Card Reader Controller
