Introduction

Help on debugging removable device issues.

How to report

When reporting a problem with removable devices, such as USB storage devices ("keys", hard drives, card readers, music players, digital cameras, etc.), please do the following steps:

  1. disconnect the device

  2. killall gnome-volume-manager

  3. In Ubuntu 5.10 (Breezy Badger) and older

    • gnome-volume-manager 2>&1 | tee gvm.log

    In Ubuntu 6.06 (Dapper Drake) :

    • gnome-volume-manager -n 2>&1 | tee gvm.logBR

    and in another terminal

    • sudo udevmonitor -e | tee udev.log

  4. connect the device
  5. wait a few seconds
  6. Press Control-C to stop the foreground gnome-volume-manager
  7. In Dapper press Control-C to stop the udevmonitor

  8. lshal > lshal.txt

  9. dmesg > dmesg.txt

  10. ls -l /dev/sd* > devices.txt

  11. attach gvm.log, lshal.txt, devices.txt, dmesg.txt and udev.log (dapper only)

to the bug report

  1. Press Alt-F2 and type gnome-volume-manager to get your background g-v-m back (or just log out and back in again)

  2. paste the output of id into the bug report

  3. paste the output of id hal into the bug report

  4. paste the output of id haldaemon into the bug report

  5. paste the output of uname -a into the bug report

In easy cases this is everything that is needed. However, you might be asked for a "hal debug output"; please do the following steps to get it:

  1. disconnect the device

  2. sudo killall hald

  3. In Warty and Hoary:

    • sudo hald --drop-privileges --daemon=no --verbose=yes 2>&1 | tee hal.log

    In Breezy and Dapper:

    • sudo hald --daemon=no --verbose=yes 2>&1 | tee hal.log

  4. wait until the flood of messages settled
  5. connect the device
  6. wait again until no messages appear any more
  7. press Control-C to stop the foreground hal
  8. Restore the background hal:

    • sudo /etc/init.d/dbus-1 restart (in Warty and Hoary)

    • sudo /etc/dbus-1/event.d/20hal start (in Breezy and Dapper)

  9. attach hal.log to the bug report
  10. Restart your desktop session
