On my HP 625 Laptop running Ubuntu 14.10 with kernel 3.16.0-28, the SD card reader stopped working after some time. The last actions related to this device were installing exfat-fuse and exfat-utils to mount SDXC cards. This was successful, but after copying some files from the card to hard drive, the device stopped working.

Now, there is nothing showing up in cat /proc/partitions (i.e. the output is identical before and after inserting a card (SD or SDXC, doesn't matter)).

The output of sudo lspci does not seem to have an SD card reader included:

The output of lsusb doesn't look like it contains anything card reader related either:

dmesg | grep -i "card" only outputs sound card related stuff.

Uninstalling exfat-fuse exfat-utils does not change anything, and neither does reinstalling the packages.

The device is enabled in BIOS.

It seems like the drivers for this device disappeared, doesn't it? How do I re-enable this?

  • If you have Windows, go into that and see if the SD reader is detected. I think it may have broken.

  • Card readers are almost always attached via USB, so try lsusb instead of lspci.

  • @Cmdr I added the output, but I guess it's not helpful.

  • @Zacharee1 I don't have an alternative OS on this machine.

    That's the thing about hardware, though. It fails when least expected. I'm going to read through your question again, just to see if maybe it is software.

Try this, your machine is now on, then:

  1. Pop slowly out and then slowly in sd-card.

  2. Type this into terminal

    sudo apt-get install --reinstall udev*

Then when finish then repeat with 1. and then after this reboot your machine or shut completely down and boot up again without being online.

(the latter two lines are meant as in case sd-card would still not be recognized somehow you should not be sudo in the moment you are online).
