Sansa m250 with Ubuntu 9.04

Ubuntu 9.04 did not let me see the files on my Sansa m250 mp3 player. It detected it as a media player but I could not see its file system. I got it to work based on info in item #7 in this forum post by editing this file:

/usr/share/hal/fdi/preprobe/10osvendor/20-libgphoto2.fdi

I used gksudo nautilus to open a root file manager session. Then I made a backup copy of the above file in a directory under my home directory. Next I opened the file in gedit, commented out the section pertaining to Sansa devices, and saved the file.

Instead of restarting hal I just restarted the machine.

Now when I connect the Sansa player I can see and copy files as I please.
