Well you can follow the instruction to solve the matter.
First of all you have to install building tools. Use following command on the terminal
Now download the drivers from the official website.
$ sudo apt install build-essential
Now Change to the directory where you needed and extract the tar ball to process further.
Now you have to build the module and install the same.
$ cd <working directory path>
$ tar zxvf <path to downloaded file>/keucr.tgz
$ cd keucr
Once you have finished you should insert the SD card. See whether it appears in the computer or not. Write the following code on the terminal and see whether keucr.ko module is present or not.
make -C /usr/src/linux-headers-`uname -r` M=`pwd`
$ sudo make -C /usr/src/linux-headers-`uname -r` O=/lib/modules/`uname -r`/build M=`pwd` modules_install
$ sudo depmod -a
$ sudo update-initramfs -u -k `uname -r`
I hope above mentioned steps will help you out to solve the problem.
$ modprobe -l keucr
$ ls /lib/modules/`uname -r`/build/extra
