Even tho Ubuntu 9.04 (Jaunty Jackalope) was released only a few days ago, I’ve been running it without issue on most of my systems since alpha (What can I say, I like to live on the edge). Well, nearly without issue.
When plugging in my Sansa e260 into either my Thinkpad or desktop systems the Sansa would not mount in either mode.
Tailing /var/log/syslog/ (tail -f /var/log/syslog) revealed this;

After some digging around, I found a bug report at https://bugs.launchpad.net/ubuntu/+bug/345916 points to the modification of a file under /usr/share/hal/fdi/preprobe/10osvendor/. Looks easy enough…
- Open a Terminal window (Accessories > Terminal)
- cd /usr/share/hal/fdi/preprobe/10osvendor/
- sudo cp 20-libgphoto2.fdi 20-libgphoto2.fdi.backup
- sudo nano 20-libgphoto2.fdi
- Remove all entries between line 6633 and line 6764
You can use the shortcut Ctrl-k to cut lines. Make sure the <match> tags are correctly nested and closed otherwise we’ll get all sorts of weird errors. - Use Ctrl-x to save and exit nano
Now reconnect the Sansa. If you’re still tailing syslog then you should see something like this;

After preforming updates, you might have to re-edit the 20-libgphoto2.fdi file, as your changes may be over written by newer packages.
As always, your mileage may vary.
