# Enable the detection and operation of a SDRPlay device:

# Create a udev file in /etc/udev/rules.d

# Create the following file: 66-mirics.rules

SUBSYSTEM=="usb",ENV{DEVTYPE}=="usb_device",ATTRS{idVendor}=="1df7",ATTRS{idProduct}=="2500",MODE="0666"

Listing the directory:

cd /etc/udev/rules.d
ls -l 66-mirics.rules
-rw-rw-r-- 1 root root 107 Jun 19 20:56 66-mirics.rules

# if the security isn't -rw-rw-r-- then execute the following command:
sudo chmod 664 66-mirics.rules

# Check the contents of the file
# Execute: 
cat 66-mirics.rules
# This should show the line from above

# Remove the sdr from the system

# Execute the following command:
sudo service udev restart

# Re-insert the sdr

# Execute, you should see the sdr being connected and recognised.
sudo dmesg -wT

# Execute CTRL-C to stop the dmesg command
CTRL-C 

# Execute:
SoapySDRUtil --probe="driver=sdrplay"

# Please share the output

 # Execute the following command to install the mirics drivers.
 sudo apt-get install soapysdr-module-mirisdr

 # Now if you run the SoapySDRUtil --info again, you should see the mirics
 #  drivers

 # Make sure you configured the above 66-mirics.rules before you attempt to
 #  use the SDRPlay
