For the first month or so that I had my KC60, it worked perfectly fine, no problems.
Suddenly, one day, I noticed the LEDs blinking when I woke up in the morning. After unplugging and replugging the keyboard, I find that none of the keys work, barring the top row, Q, W, E and for some reason Tab. All the LEDs seem to work.
I've tried a whole bunch of things, and pressing the button in the back when plugging in, all kinds of stuff. Do I need to go into the firmware to fix this?
