> The function driver may re-enable an endpoint before the End Transfer
> command issued on ep disable completes. The no-op Start Transfer issued
> on ep enable then fails with "No Resource".
>
> Only stream endpoints need the no-op Start Transfer to initiate a
> stream. Other bulk and interrupt endpoints start their transfer when a
> request is queued. Skip it for those endpoints, and move it to a helper
> to be reused.
