try :
%users ALL=/bin/umount NOPASSWD: ALL
or maybe :
%users ALL=/bin/umount device NOPASSWD: ALL
where "device" is whatever the usb drive is mounted as.
Not workable if "device" is variable.
Alternately, you could do :
su
(enter password)
umount ...
As to why you are having the problem :
It means that the drive was mounted with root privileges, or the
privileges of another user.
Thus it is requiring root privileges (or that of the other user) to unmount.
Was it plugged it when the system was booted ? That could cause it to
have root privileges.
Is it in a line the /etc/fstab file ?
(if so, you just have to add the option "users" in the comma-separated
list in the third position in the line.)
Or it could be a bug.
