Do the processes which access the filesystem (scsi_eh_5 and usb-storage) disappear after some time? A common reason for the issue you described are indexing processes (like nepomuk, strigi, ...) which read the content of a USB disk in the background. You should check which processes read/write to the device by executing 'lsof <device>' (e.g. '/dev/mapper/udisks-luks-uuid-1234-5678-90ab-cdef12345678-uid1000') and 'fuser -m <mount_point>', (e.g. '/media/fedcba09-8765-4321-fedc-ba09-87654321fedc').
