Connect your device and type the following in the terminal

$ sudo dmesg && lsusb
These commands list the Vendor and Product ID's which are required for the udev rule.
Once you have the ID's create for each serial USB device a file in directory
/usr/lib/udev/rules.d
E.g. for Pegasus Power Box:
$cat 99-indi_aux_ppb.rules
SUBSYSTEM=="tty", ATTRS{idVendor}=="0403", ATTRS{product}=="*PPB*", SYMLINK+="ttyPPB", MODE="0666"
SUBSYSTEMS=="usb", ATTRS{idVendor}=="0424", ATTRS{idProduct}=="2517", MODE="0666"

Then either reboot your PC/RPI or type
$sudo udevadm trigger

Once you attach a the Pegasus Power Box, the device gets a symbolic link: /dev/ttyPPB which is persistant and can be accessed by this symbolic link.
