'lsusb -v' will show a unique serial number (iSerial) for each device. I have three SIIG USB Serial adapters.

I have to manually unplug all three, then plug them using the order I want from 0 to 2. I can live with either a method to fix ttyUSB# to either the iSerial (preferred) and/or the Bus+Device number. -- Two USB serial adapters get different /dev/ttyUSBn names after reboot https://bugs.launchpad.net/bugs/107208 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
