+           Many controller and gadget drivers will print some 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.
