I think it still gives the possibility for failure. I would rather not
take that until all gadget drivers are fixed. We can help you doing that
and we only change driver->speed after all gadget drivers have their
"sensible defaults" SuperSpeed descriptors.

What do you say ? Other than that, the module parameter is, like Alan
Said, useful for debugging, so we might as well keep it.
