The problem remains. It has nothing to be with cue because it doesn't reach the BIOS screen. We dont use CUE by the way. It must be something related to the keyboard hardware itself. Even though I followed Corsair instructions and... the problem does not fix.

Yes you are right. My pc doesn't boot. It gets freezed before the Bios screen. If I unplugg the K55 it boots.

Sorry, I deleted part of the text. Yes that's the problem. Windows is updated so I think USBs are fine but it cannot be a drivers problem beacuse it freezes even before the BIOS screen.

Just bought a new K55 keyboard earlier this week and things were great for the first two days, today though has been a big headache. It gets freezed before Bios screen. This is only happening when my K55 is plugged in to any, USB 3.0 or USB 2.0, port. The only solution that's actually done anything is unplug/plug the K55 back in or turn off/on again pressing On button. My computer boots perfectly fine with another keyboard plugged in so long as the K55 isn't plugged in. However, when I restart instead of a full shutdown, my PC boots perfectly fine with the K55 plugged in. Anyone with this issue?

Any answer??

This is a copy/paste message from other site that explains perfectly my problem. Just bought a new K55 keyboard earlier this week and things were great for the first two days, today though has been a big headache. What's happening is, when going from a COLD Boot, my computer hangs before Bios. This is only happening when my K55 is plugged in to any, USB 3.0 or USB 2.0, port. The only solution that's actually done anything is unplug/plug the K55 back in or turn off/on again pressing On button.
