You misunderstood my question. I was asking what specifically, if anything, was changed in the firmware to allow skipping reset/sleep part of device initialization on newer parts during resume process. Because of there were no specific changes I would say let's not do a quirk and change the driver to skip reset on resume. Thanks. -- Dmitry
