IKBC Fullsize CNC Aluminum RGB Mechanical Keyboard

I think that light is actually the repeat-key sensitivity for when you hold a button down. I think that it changes color when you press the fn key with number line 1-4, 1 for normal (off), 2-4 have different colors.

I think that my USB port went out. Can anyone help me source the part? My keyboard isn't lighting up or registering keys, and Windows says that it's drawing too much power.

I can't seem to get the little indicator under the CAPS LOCK key on my MF108 to illuminate when the caps lock is on. The little light over the number keypad on the right does light up, but the little dot light on the caps lock key doesn't. Any ideas?
