Thanks. The strace shows that udev both received and sent the events for /dev/sdc1, and also mknod()ed /dev/sdc1 successfully. So either the problem only happens sometimes, or something went wrong when you inserted the device while reporting the bug initially. So I don't believe the original UdevMonitorLog.txt and DKDisksMonitorLog attachments any more.
Can you please unplug the drive, then open a terminal, and do devkit-disks --monitor-detail > /tmp/dkd.log 2>&1 & udevadm monitor -e --udev > /tmp/udev.log 2>&1 & gvfs-mount -oi > /tmp/gvfs.log 2>&1 then plug in the drive, wait for 20 seconds. Close the terminal, and then attach /tmp/dkd.log, /tmp/udev.log, and /tmp/gvfs.log here. -- USB flash drive does not mount automatically https://bugs.launchpad.net/bugs/479206 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
