It's better to use this device, since it won't change when you plug in
an extra USB stick/drive.

I prefer 'mode 0660 group usb' in principle, but that is personal.

I prefer to have a script do the mounting, so I can add some sane flags
to mount_msdosfs that you cannot put in options/fstab AFAICT, like 
'-m 644 -M 755 -l -o noatime -o sync -o noexec -o nosuid'.
