Look at the symlink example. And the debugging logger scripts.
I was reading those examples but i did not find any way to identify every
USB-Serial in a unique way.
Let's try again and post the results.
I've heard reports that for some cheap adapters it is not possible. They don't
bother to set the serial number to something unique and so you can end up with
adapters that report absolutly identically (not just USB-Serial, but they are in
the category that is more likely to be that cheap)
If the USB device does not provide a unique identifier per device, you are left
with the order that they are plugged in, what bus they are plugged into, or just
a race condition about which one replied first.
It's an unfortunante reality about USB
