agetty is running and it got the "57600" option. systemd is only involved in starting that job, it does not actually set up ttys by itself. So removing the systemd task.
Can you try to stop that job and call agetty manually with the same parameters? Does that work? If so, then apparently something else is interfering with the serial parameters at boot/when the device appears. If it also does not work, this sounds like a bug in agetty. Reassigning to util-linux as you are using agetty, not mgetty. ** No longer affects: systemd (Ubuntu) ** Package changed: mgetty (Ubuntu) => util-linux (Ubuntu) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1571500 Title: console port speed impossible to set on ttyUSB0 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/util-linux/+bug/1571500/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
