No , but I have 6 computer and mac book. Corsair k55 and k70 not work. My 3 other keyboard is fine in all computer.
It have to be usb handshake , because if you unplug keyboard , all software witch poll usb hardware started faster. And leds freeze or other light or key not work problem are firmware problem. I tested by powered keyboard directly by using adjustable powersupply, still caps and num leds freeze after ~5-15 min.
It is not chipset usb driver or bios problem, that is pull **** , corsair support do not know where is problem and ask customer do something random.
If loading USB tracer software:

, everyone can be see failed handshake, if compared other manufactured kb.
shame corsair !
