      usb: Assure Get Descriptor request is in separate microframe · ef71290b
      Marek Vasut authored
      
      The Kingston DT Ultimate USB 3.0 stick is sensitive to this first
      Get Descriptor request and if the request is not in a separate
      microframe, the stick refuses to operate. Add slight delay, which
      is enough for one microframe to pass on any USB spec revision.
