Public bug reported: Until 2.6.31.5 the mainline kernel contained a bug whereby repeated opens of usb-serial devices using the ftdi_sio driver would fail to receive any data unless opened with the O_NONBLOCK flag set. Trying to fnctl( ) an already opened port would not resolve the issue.
This bug was fixed in the 2.6.31.5 update to the ftdi_sio driver and currently still affects the Ubuntu 2.6.31-14 kernel. There was a not-insignificant update consisting of 4 patches to the ftdi driver in the .5 stable patch set. Can someone update this driver please? http://lkml.org/lkml/2009/10/16/245 http://lkml.org/lkml/2009/10/16/220 http://lkml.org/lkml/2009/10/16/197 http://lkml.org/lkml/2009/10/16/198 ** Affects: linux (Ubuntu) Importance: Undecided Status: New -- ftdi serial driver broken in linux-image-2.6.31-14-generic (2.6.31-14.48) https://bugs.launchpad.net/bugs/460857 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
