Since i have the very same KB in use with my Skylake build (full specs with pics in my sig), here's one secret way to try:
Open up Corsair iCUE and look if it detects your KB. My guess is that it does not. If so, press following key combo: F1 + Win lock key (upper right corner).
This key combo activates Legacy mode on your KB and after 5 or so seconds, LEDs also lit up, which red backlight, except WASD and arrow keys who have white backlight. Wait for 10 or so seconds and press F1 + Win lock key combo again. That reverts back to the normal mode and after 10 or so seconds, iCUE should detect your KB again, so that you can use your KB with custom lighting and macro profiles as always.
