Ubuntu: SD-card reader suddenly stopped recognizing cards



Question:

Recently my sd-card reader stopped working.

The weird part: 5 minutes earlier etcher successfully wrote an image to an sd-card. After wanting to write another imagefile, no sd-cards could get mounted/unmounted/recognized anymore.

The device refusing to work properly:

#$ sudo lspci -v    ...  03:00.0 Unassigned class [ff00]: Realtek Semiconductor Co., Ltd. RTS525A PCI Express Card Reader (rev 01)      Subsystem: Dell RTS525A PCI Express Card Reader      Flags: bus master, fast devsel, latency 0, IRQ 129      Memory at dd100000 (32-bit, non-prefetchable) [size=4K]      Capabilities: [80] Power Management version 3      Capabilities: [90] MSI: Enable+ Count=1/1 Maskable- 64bit+      Capabilities: [b0] Express Endpoint, MSI 00      Capabilities: [100] Advanced Error Reporting      Capabilities: [148] Device Serial Number [xx-xx-xx-xx-xx-xx-xx-xx-xx]      Capabilities: [158] Latency Tolerance Reporting      Capabilities: [160] L1 PM Substates      Kernel driver in use: rtsx_pci      Kernel modules: rtsx_pci    ...  

Since the device was working like a litteral 5 minutes before, I'm assuming an error in either the driver/module or an unremoved device lock which I can't find.

There are several things I've tried to fix it and it failed:

  • Turning computer off and on again
  • Since the sd-cards used were micro sd-card with adapter, several adapters were tried
  • Several sd-cards were tried (in case the card itself broke)
  • An online suggestion of reinstalling udisks2
  • An online suggestion of sudo apt-get install --reinstall udev*
  • Using a LiveCD on a usb-drive
  • Using another usb sd-card reader

More information:

I'm currently running Linux Mint 18 with Xfce desktop environment on my Dell Precision 5510

  Linux kernel:      4.4.0-103-generic     Version:      #126-Ubuntu SMP Mon Dec 4 16:23:28 UTC 2017   

The running modules which relate to the sd-card reader are:

#$ lsmod  Module                  Size  Used by    ...  rtsx_pci_ms            20480  0  memstick               20480  1 rtsx_pci_ms  rtsx_pci_sdmmc         24576  0  rtsx_pci               53248  2 rtsx_pci_ms,rtsx_pci_sdmmc    ...  

EDIT:

  • Using an other sd-card reader (via usb) worked after all, I guess I shouldn't conclude something, if it is not working with the cheapest of hardware.


Solution:1

Own Answer:

Using an external sd-card reader worked after all. The internal SD-card reader of my machine just broke, which hasn't anything to do with any config or software.
