I recently upgraded to ubuntu 16.04 and my SD card reader is not working. The system does not detect the reader at all. The output of lsusb is fairly uninformative:

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

So I don't even know what sd card reader model I have. I'm using an ideapad u430.

Probably an installation-issue which can be resolved with re-installation?! This would concern package udisks2.

1. 
   

   Reinstall package udisks2

   
   
   

   sudo apt-get install --reinstall udisks2
   

   
   


2. 
   

   Reboot the machine

   
   
   

   systemctl reboot
   

   
   

SD cards should be recognized then, after inserting them (in and out and in cautiously).

I am guessing you have Realtek card reader?

Download the Linux driver for your Realtek device for example rts5159
Open a new terminal session

Install the driver. Run the following commands:

cd where-your-driver-was-downloaded-extracted 
make
sudo make install
sudo depmod

If you have installed a Card reader lsusb should give you something like:

Bus 001 Device 005: ID 0bda:0129 Realtek Semiconductor Corp. RTS5129 Card Reader Controller
