  Have you tried running the GUI as 'root'? For example, using the 'sudo' command.

  yes I am running it as root

  
  

  sudo ./OpenBCI_GUI 
  

  
  

  although I did have to change the permissions of the /dev/ttyUSB0 to get the Python library to connect ( as per the other forum thread )

  
  

  thx!
