Do you have any programs with files open in /mnt/usb? Or might you have a file browser or shell currently in /mnt/usb?

I close all browser and folders/files under my /mnt/usb. NO open files in my /mnt/usb. Can you give tips in this...

"fuser -v /mnt/usb" to find out what's open. "umount -l /mnt/usb" if that doesn't work. "man fuser", "man umount" for info.
