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. stop gvm BR

    • killall gnome-volume-manager

  3. start gvm and capture output BR

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

  4. if that doesn't work, try BR

    • /usr/lib/gnome-volume-manager/gnome-volume-manager -n 2>&1 | tee gvm.log

  5. and in another terminal, start udevmonitor and capture output BR

    • sudo udevmonitor -e | tee udev.log

  6. connect the device
  7. wait a few seconds
  8. press Control-C in the first terminal to stop the foreground gnome-volume-manager
  9. press Control-C in the second terminal to stop the udevmonitor

  10. capture lshal, dmesg and ls the attached volumes BR

    • lshal > lshal.txt BR dmesg > dmesg.txt BR 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

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

  13. paste the output of id into the bug report

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

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

  16. 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. stop hald BR

    • sudo killall hald

  3. start hald while capturing its output BR

    • 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 more messages appear
  7. press Control-C to stop the foreground hal

  8. restore the background hal: BR

    • sudo /etc/init.d/dbus-1 restart (in Warty and Hoary)BR OR BR sudo /etc/dbus-1/event.d/20hal start (in Breezy, Dapper, Edgy and Feisty)

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