    Subject[PATCH 4.9 35/80] USB: Add USB_QUIRK_DELAY_CTRL_MSG and USB_QUIRK_DELAY_INIT for Corsair K70 RGB RAPIDFIRE
    Date
    From: Jonathan Cox <jonathan@jdcox.net>

    commit be34a5854b4606bd7a160ad3cb43415d623596c7 upstream.

    The Corsair K70 RGB RAPIDFIRE needs the USB_QUIRK_DELAY_INIT and
    USB_QUIRK_DELAY_CTRL_MSG to function or it will randomly not
    respond on boot, just like other Corsair keyboards
