I am also having this same issue with the K55. I have a Dell Optiplex 990 mt that i am using. It is happening with it in any USB port. I have 100% narrowed it down to the keyboard, tried it with and without iCUE installed and even with a fresh install of windows. Anybody with this issue found any fixes for it? Pretty annoying to have to unplug my keyboard any time i make hardware adjustments. Not to mention, getting into the bios from a cold boot is a nightmare when you have a fraction of a second of a window to plug in the keyboard and press the necessary keys. Honestly, this is making me not want to purchase any other Corsair products.
