I agree that my Ublox 7 does not display a serial number, neither does my GlobalSat BU-353 nor any of my devices that use the Prolific chip set. FTDI however do offer serial numbers as you can see.
I would not want you to go to the effort just for me, I am perhaps one of only a handful of happy OpenPlotter uses who use multiple identical serial devices for which the serial number attribute is not blank. If in future it means I can't remember the devices by vendor, product, serial then I can live with it. It might be worth changing the panel option "Remember device (by vendor, product, serial)" to ..vendor, product, model so that it is clear that the serial number is not a factor.
Also the message shown in the image in post #29 is a little misleading - Device with duplicate vendor and product must be set to "Remember port". You can see in that picture that I already have two devices correctly set up with identical vendor and product ids (0403, 6001). If the message were to mention the third attribute then it would be accurate.
Thanks very much once again.
The output of the command you suggest does not render the information in the format shown in your post so here is the data for the three cables I use from the lsusb command:
Output of the udevadm info -a -n /dev/ttyUSB0 command is very verbose:

Code:
Udevadm info starts with the device specified by the devpath and then
walks up the chain of parent devices. It prints for every device
found, all possible attributes in the udev rules key format.
A rule to match, can be composed by the attributes of the device
and the attributes from one single parent device.
