Kivy - Unable to open device "/dev/input/event7" on Ubuntu, no permission

I'm using Ubuntu 16.04 and every time I run any Kivy App (I'm new to both Ubuntu and Kivy), I get the message: 

[WARNING] [MTD] Unable to open device "/dev/input/event7". Please ensure you have the appropriate permissions.

It works normally, I would just like to know why the message appears and if I can get rid of it. It doesn't matter if I run the app from PyCharm or Terminal. When I run it in Windows, everything is fine without this message.

This message appears because Kivy queries each input device to see if it should listen to it. It doesn't matter that it failed to access this one, it's normal.

It's a minor bug that this message is printed each time, since it isn't really necessary, but nobody has ever got around to fixing it.
