These comments are excessive.

When someone calls ops->stop() what are they supposed to think the
thing does? Open a can of tuna? Mow the lawn? Wash the dishes? No,
it stops the thing. Everyone understands that and you don't have to
explicitly say it.

Saying "stop the hardware" does not add anything to the source code
that is not already implicitly there. They just take up space and
keep more useful information from being displayed at once on the
screen. Please remove all of these things.
