Another option you may want to explore is writing a little script to
detect which physical device is linked to which serial port, by
looking at /proc/bus/usb/devices (iirc), and then taking the
appropriate action, perhaps by making a symlink (/dev/TTYUSB0 ->
/dev/MyTTY1, /dev/TTYUSB1 -> /dev/MyTTY0 if they come up in reverse
order, for example). I did something similar to this a while ago for
Tosha's wacom tablet (before the driver improved and it became no
longer necessary).
