Public bug reported:
At random times the serial/tty port to my Arduino (teensy 3.2) is being
opened by WebKitNetworkProcess and not being released.
Ubuntu 18.04.1 LTS
libwebkit2gtk-4.0-37: Installed: 2.22.2-0ubuntu0.18.04.2
expected to be able to open/access the tty associated with my Arduino
got blocked because it's open by WebKitNetworkProcess
The arduino implements a USB serial device. Unplugging the cable and
plogging it in again causes a new device name to be assigned since the
one held by WebKitNetworkProcess is still in use.
