You might be able to do something to differentiate between them if you
plug them into different hubs, and look for the hub ID as well as the
ttyUSB device. Many PCs have more than one internal hub installed,
here's my laptop:

Bus 002 Device 002: ID 8087:0020 Intel Corp. Integrated Rate Matching Hub
Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
