This is a note to let you know that I've just added the patch titled

usb: quirks: Add delay-init quirk for Corsair K70 LUX RGB

to my usb git tree which can be found at
git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb.git
in the usb-linus branch.

The patch will show up in the next release of the linux-next tree (usually sometime within the next 24 hours during the week.)

The patch will hopefully also be merged in Linus's tree for the next -rc kernel release.

If you have any questions about this process, please let me know.

Following on from this patch: https://lkml.org/lkml/2017/11/3/516,
Corsair K70 LUX RGB keyboards also require the DELAY_INIT quirk to start correctly at boot.

Dmesg output:
