Notes / Warnings

  1. For device controllers that have hardware assistance to enable the device address after the status stage has completed, the assignment of the device address can also be combined with enabling the device address mode.
  2. For device controllers that change the device address immediately, without waiting the status phase to complete, see USBD_DrvAddrEn.
