FroboMind:Tutorials:Using udev rules for USB-serial interfaces
From FroboMind [www.frobomind.org]
Using USB-serial interfaces in robotic systems often creates problems because linux enumerates the device names based on the time of inserting the interface. Also by default access to the serial devices requires root privileges.
This instruction video describes the problems and shows how to solve them by creating a udev rule for each interface.
