Subject: [PATCH] Add USB_QUIRK_DELAY_CTRL_MSG quirk for Corsair K70 RGB
Date:   Wed,  2 Jan 2019 18:37:44 +0000
Message-Id: <1546454264-11561-1-git-send-email-jackstocker.93@gmail.com>
To:     unlisted-recipients:; (no To-header on input)
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

To match the Corsair Strafe RGB, the Corsair K70 RGB also requires
USB_QUIRK_DELAY_CTRL_MSG to completely resolve boot connection issues
discussed here: https://github.com/ckb-next/ckb-next/issues/42.
Otherwise roughly 1 in 10 boots the keyboard will fail to be detected.
