Installing the software
Install Dependencies via apt:

sudo apt update

Install RTL-SDR-Kerberos Drivers

Our Kerberos RTL-SDR driver branch contains code for slightly modified Osmocom RTL-SDR drivers that enable GPIO, disable dithering, and disable zerocopy buffers which seems to cause trouble on some ARM devices.

sudo apt-get install libusb-1.0-0-dev git cmake 

git clone https://github.com/rtlsdrblog/rtl-sdr-kerberos

cd rtl-sdr-kerberos
mkdir build
cd build
cmake ../ -DINSTALL_UDEV_RULES=ON
make
sudo make install
sudo cp ../rtl-sdr.rules /etc/udev/rules.d/
sudo ldconfig

echo 'blacklist dvb_usb_rtl28xxu' | sudo tee --append /etc/modprobe.d/blacklist-dvb_usb_rtl28xxu.conf

Now reboot the Pi.
Test 4x Tuners

At this stage we recommend first testing your four tuners with rtl_test. Open four terminal windows, or tabs, and in each window run "rtl_test -d 0", "rtl_test -d 1", "rtl_test -d 2" and "rtl_test -d 3". Ensure that each unit connects and displays no errors.
