one more thing: setserial describes a 16550A uart and your lshw output describes a 16550. i have no idea whether that makes a difference, but setserial allow setting a 16550.
from your lspci output: "Kernel driver in use: serial"; this is not a module, correct? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1087519 Title: Serial port ttyS4 doesn't work in 12.04 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+bug/1087519/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
