Assuming you're talking about USB MSD function, the store exposed as
MSD is unmounted when detecting USB connect (in other words it is no
longer accessible by the device, *only* by the host). When
disconnecting the device, the driver will force a re-examination of the
file sytem, ultimately resulting in remounting the store so that it is
accessible by the device again.
If this is not how your device responds something is not working OK
(obviously). Exactly what goes bad is impossible to say since you don't
give any useful details (debug output?). The first thing I'd do would
be to make sure the USB function controller driver correctly detects
cable attach/detach.
