    Subject[PATCH 3.18 34/38] USB: Add delay-init quirk for Corsair K70 LUX keyboards
    Date
    3.18-stable review patch.  If anyone has any objections, please let me know.

    ------------------

    From: Bernhard Rosenkraenzer <bernhard.rosenkranzer@linaro.org>

    commit a0fea6027f19c62727315aba1a7fae75a9caa842 upstream.

    Without this patch, K70 LUX keyboards don't work, saying
    usb 3-3: unable to read config index 0 descriptor/all
    usb 3-3: can't read configurations, error -110
    usb usb3-port3: unable to enumerate USB device
