OK, looks like there was as well a problem with the (custom, not ubuntu related) program setting up the serial port under certain circumstances - with the fix for this bug and a fix of the custom program, my FHZ 1300 PC device now works correctly with /Ubuntu 2.6.35-25.44-generic 2.6.35.10/ as well.

[Bug 690798] Re: arduino USB serial device breaks on lucid kernel upgrade
After watching & waiting a bit, I've seen no more errors of the type I described in #16. I've rebooted and done a replugging test or two and it's all been solid. Coincidentally one of my 1-wire sensors died but I got quite different error messages from that and it seems clear that the ftdi_sio module was not at fault. I'll give it a few more days and let you know if I see a recurrence. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/690798 Title: arduino USB serial device breaks on lucid kernel upgrade -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 690798] Re: arduino USB serial device breaks on lucid kernel upgrade
Just to be clear, 677aeafe19e88c282af74564048243ccabb1c590 is NOT in the lucid kernel, while 6a1a82df91fa0eb1cc76069a9efe5714d087eccd is. So lucid is carrying a patch that has been reverted upstream and as described, changes the kernel back to the previous way of working. Git says it was added to lucid in Ubuntu-2.6.32-24.39-110-g55b5b54, which coincides with when the device stopped working. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/690798 Title: arduino USB serial device breaks on lucid kernel upgrade -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 690798] Re: arduino USB serial device breaks on lucid kernel upgrade
Had a look at this bug prompted by a request from Alex as I've had some modest experience with Arduino devices and USB serial interfaces as well, albiet a long time ago. I _do_not_ consider myself expert in either however! :) Couple of observations... Firstly, the comments in the patch referenced are: - 8< - 8< - 8< - 8< - 8< - 8< - This reverts commit 6a1a82df91fa0eb1cc76069a9efe5714d087eccd. RTS and DTR should not be modified based on CRTSCTS when calling set_termios. Modem control lines are raised at port open by the tty layer and should stay raised regardless of whether hardware flow control is enabled or not. This is in conformance with the way serial ports work today and many applications depend on this behaviour to be able to talk to hardware implementing hardware flow control (without the applications actually using it). Hardware which expects different behaviour on these lines can always use TIOCMSET/TIOCMBI[SC] after port open to change them. - 8< - 8< - 8< - 8< - 8< - 8< - So it is significant in that it changes behaviour of the kernel back to the way it used to be - ie there was only a short window when the HW flow control lines worked "the other way" It's also signed off by gkh and a couple of other folk who have a good deal of expertise with serial devices. Secondly, the FTDI chips in question are used in a multitude of devices, so if the behaviour had long been incorrect, it would, presumably, have affected many other bits of hardware, not just Arduinos. I suspect some modification to the user space app to explicitly set the HW lines as required may be the correct solution rather than reverting this patch. Happy to have more of a dig if need be - do have Arduino hardware about and can fish out a Lucid machine if need be. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/690798 Title: arduino USB serial device breaks on lucid kernel upgrade -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 690798] Re: arduino USB serial device breaks on lucid kernel upgrade
This is the code that gets loaded onto the arduino. The reporter says that a basic "hello world" arduino program might be sufficient to prove breakage too, as long as the "hello world" does both input and output. ** Attachment added: "dishIR.pde" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/690798/+attachment/1767095/+files/dishIR.pde -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/690798 Title: arduino USB serial device breaks on lucid kernel upgrade -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
