Before touching /etc/udev/rules.d, only one USB Serial adapter would be assigned ttyUSB0. The others would not be mapped in.
After adding the udev rules below, they are now working as expected, but the computer required a power cycle or the USB Serial adapters required being unplugged and replugged back in before they would communicate with their serial devices. The following was helpful. http://www.reactivated.net/writing_udev_rules.html#udevinfo Thank you for the help. # /etc/udev/rules.d/50-local.rules # /dev/ttyUSB0 SUBSYSTEMS=="usb", ATTRS{manufacturer}=="Generic", ATTRS{product}=="USB to Serial Converter", ATTRS{serial}=="OCBPJ9HM", KERNEL=="ttyUSB[0123]", SYMLINK+="powercom" # /dev/ttyUSB1 SUBSYSTEMS=="usb", ATTRS{manufacturer}=="Generic", ATTRS{product}=="USB to Serial Converter", ATTRS{serial}=="OCBAKZ7N", KERNEL=="ttyUSB[0123]", SYMLINK+="smartups", MODE="0660", GROUP="nut" # /dev/ttyUSB2 SUBSYSTEMS=="usb", ATTRS{manufacturer}=="Generic", ATTRS{product}=="USB to Serial converter", ATTRS{serial}=="OCBQH84W", KERNEL=="ttyUSB[0123]", SYMLINK+="usrobotics" -- 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
