I checked all wiki instructions and previous posts in Discourse without joy.  
When inserting my LimeSDR Mini, I see it in lsusb but not LimeUtil  
$ lsusb  
Bus 002 Device 006: ID 0403:601f Future Technology Devices International, Ltd  
$ LimeUtil --update  
No devices found  
$  
Any advice?

i think you have to install the udev-rules

```
 cd LimeSuite/udev-rules
 chmod +x install.sh
```

Thanks for the input. I did that, and did it again without luck  
~/LimeSuite/udev-rules$ sudo ./install.sh  
[sudo] password for bjorn:  
~/LimeSuite/udev-rules$ LimeUtil --update  
No devices found  
~/LimeSuite/udev-rules$

I am not sure, but it is important to install all software in the right order. Maybe that’s your problem.  
it’s best if you uninstall everything first and try it with a fresh install.  
I had written a bash script for myself, maybe it will help you:

```
#!/bin/sh
if ["$(id -u)" == "0"]; then
   echo "This script must be run as normal User" 1>&2
   exit 1
fi

user="$USER"
sudo add-apt-repository -y ppa:myriadrf/drivers
sudo apt update -y
sudo apt upgrade -y

if [-d /home/$user/SoapySDR]; then
    echo " - SoapySDR already exists. Skipping it."

else
  ##sudo apt-get install soapysdr-tools -y
  git clone https://github.com/pothosware/SoapySDR.git
  cd SoapySDR || exit
  git pull origin master
  mkdir build
  cd build || exit
  cmake ..
  make -j4
  sudo make install
  sudo ldconfig #needed on debian systems
  cd /home/$user/ || exit
fi

Great script! Got it working. Thanks a lot. I had to start with a fresh Ubuntu 18.04 though. Will try to uninstall everything on the first one.

Should work fine on Ubuntu 18.04 with an install via packages from the PPA. That’s what I’m currently using…
