I have now updated the Linux kernel from 2.6.20-15-generic. After that it seams to work better, but the same kind of problem is still there. I have generated and attached some information about my system after the device has disconnected.
Thanks for working with this bug! ** Attachment added: "Log messages after device disconnect." http://launchpadlibrarian.net/8449022/ftdi_error.tar.gz -- FTDI USB Serial Device converter disconnects https://bugs.launchpad.net/bugs/122834 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
