Ubuntu 20.04.1 (amd) 中未检测到 SanDisk MobileMate USB 3.0 读卡器（0781：​​cfcb SDDR-B531）

我可以毫无问题地使用 Transcend 和 Anker microSD 读卡器，但是 lsblk 无法检测到 SanDisk MobileMate USB 3.0 读卡器。

我在 ODROID-H2+（x86-64）上运行 Ubuntu 20.04.1。

我使用的 microSD 卡是 SanDisk Extreme Pro microSDXC UHS-1（64GB）。
它在 Anker 读卡器中运行良好。

我尝试过拔掉它然后再重新插入。

我尝试移除其他 USB 设备并更改我正在使用的 USB 3.0 端口。

我确实注意到读卡器似乎比预期的要热。我猜这可能与它的尺寸小得多有关？

我试过了

$ sudo apt-get install --reinstall udisks2
$ sudo reboot

lsusb 揭示了这一点……

我认为你应该尝试安装 openct，我是从 Manjaro 上的 AUR repo 安装了它（https://aur.archlinux.org/packages/openct），在 Ubuntu 上，你可以尝试从 Github 下载代码后手动构建它（https://github.com/OpenSC/openct）。我的 SanDisk SD 卡读卡器工作正常。lsusb 的输出为：
