It is also allowed to have no serial number.

Maybe some kind of "lstty" would do.

-l  -  list all devices
-s  -  match by serial
-v  -  match by vendor
-p  -  match by product
-i  -  match by interface ID
-t  -  type [USB/PCI]

which simply output the tty number you need. Could be an API we could 
add to libusb.
