It means VFS301 driver is buggy. Recent changes just revealed this
bug. It will fail the same way on short scan or a scan with not enough

This change will break other devices. And anyway it'll fail if
application attempts to redo bad scan as I mentioned above.

Non-functional LED is a driver issue.
