! am trying to launch a JavaFX app on my beaglebone black running Debian.

When launching as the root user, the application will launch but the 
touchscreen will bug out a little bit, displaying improperly and messing up 
the touchscreen touch calibrations.

When I try and launch the app as a normal user, I get the following error 
messages as the app launches:

Udev: Failed to write to /sys/class/input/mice/uevent

      Check that you have permission to access input devicesUdev: Failed to 
write to /sys/class/input/mouse0/uevent
      Check that you have permission to access input devices

The app is then unresponsive to touch input.

How can I give a normal user permission to access the input devices?
