VIA Keyboard Configuration

To allow access to VIA, write the following to 
/etc/udev/rules.d/99-viia.rules:
KERNEL=="hidraw*", SUBSYSTEM=="hidraw", MODE="0666", TAG+="uaccess", TAG+="udev-acl"
Launching VIA without performing the above step will cause it to prompt you to add the file automatically
After creating the file, reload udev for this new rule to take effect by running the following as root:
# udevadm control --reload
You should now be able to launch the VIA app and have access to the keyboard.
