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:  Power Management version 3 Capabilities:  MSI: Enable+ Count=1/1 Maskable- 64bit+ Capabilities: [b0] Express Endpoint, MSI 00 Capabilities:  Advanced Error Reporting Capabilities:  Device Serial Number [xx-xx-xx-xx-xx-xx-xx-xx-xx] Capabilities:  Latency Tolerance Reporting Capabilities:  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. December 13, 2017 at 2:37 am #35484 Anonymous Answer 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.
