help
Many controller and gadget drivers will print verbose debugging
messages if you use this option to ask for those messages.
Avoid enabling these messages, even if you're actively
debugging such a driver. Many drivers will emit so many
messages that the driver timings are affected, which will
either create new failure modes or remove the one you're
trying to track down. Never enable these messages for a
production build.
