    Subject: [usb] VBUS state in HNP
    Top
    Dear All,

    When a device starts HNP, did it drive vbus all the
    time? Did it still drive VBUS to supply power even
    after its role transfer from a_host to a_peripheral?

    If the description has misunderstanding, please refer
    to attach file.

    Thanks lot!
