Serial/USB Controllers

If direct connections are desired (default connections use gcaps), add the user to the dialout group for access to serial and USB devices. Restart for changes to take effect.

sudo usermod -aG dialout $USER

Done!

gclib has been added to system include paths, and gcaps is ready for connections.
