I set my fineoffset rule to:
SUBSYSTEM=="usb", ATTRS{idVendor}=="1941", ATTRS{idProduct}=="8021",
MODE="0666", GROUP="plugdev", SYMLINK+="weather"
That way it is always /dev/weather regardless of the ttyUsb it is attached
to.
ll /dev/weather
lrwxrwxrwx 1 root root 15 Nov 17 09:26 /dev/weather -> bus/usb/002/002
