I have the Corsair K55 and this is happening to me, but I can't get any software and drivers for it on the main site. I've tried everything from uninstalling drivers to unplugging and re-plugging USB. It won't even work without the CUE. I've submitted a ticket. All my RGB and Media keys don't work only the top right white lights are flashing. It even says on my device and printers "Corsair K55 Bootloader"
