I've seen this error message when trying to unmount a usb device. The reason was insufficient permission for MY user. Solution was to use sudo to act as administrator:

sudo umount /mount-point

This has worked for me when using a live CD on xubuntu 9.04

I know how the umount command works.
All this time I'm using Terminal only for Copying, moving files and unmounting USB.
I was trying to figure out why I'm now facing this problem.
I'm using the same user account from months and never faced this problem before.
I just installed some packages from update manager and after restart I started facing the problem
