I disagree. This is probably part of the NFS server, to catch when
systems are being shut down and cleanly notifying and disconnecting
clients.
When the NFS mountd exports a filesystem, it gets a kernel lock on
that volume/directory (the linux NFSd is a kernel thread, not a
userspace daemon). I don't believe that the NFS server knows to
un-export filesystems on a per-volume basis because it may come or
go.
If you expect the USB device to not be always connected, then you
shouldn't export it as an NFS share. I don't think you can export an
automount either.
