try lsof /mnt/usb, or something like that. make sure you don't have a shell process (or something else) that has done "cd /mnt/usb". make sure your nautilus or other desktop apps don't have that directory open.

try eject /dev/sdc (or whatever).

i can't help you. you have to examine your system and see what's accessing the drive. there is no single simple small list of processes that could block your system from unmounting it -- it can be anything.

You must close any application that is accessing the /mnt/usb directory. For example if you have a file manager window showing this directory's contents then umount command will not work until you close the window.
