CCCant SSSSSay I Wwitnessssed it.....

I only have the non RGB K70 cherry ,  but never saw that on mine.

If it's still under warranty, Corsair offers express replacement RMA. You have to put collateral down.
 
I only had that problem after some soda was spilled on the keyboard. I managed to fix it by taking the keyboard part and cleaning it with 91% alcohol, i cleaned where the switches go down using a small paint brush. 

have called them 3 times today and get disconected every time. they said pcc crashed.
looks like my last corsair purcchacce.
thanks for the mature reply nerd.
ill try my other keyboard

I have this keyboard and have had no issues in almost a year.  I love it.
 
Remember there is a BIOS switch on the back of the keyboard.  Try all different positions and see if one works.

That is uncommon for Corsair. I would give them another call or submit a support ticket.  Corsair offers Express RMA, you don't have to talk to someone on the phone to get that kind of support.
 
 
 

 
Moving to General Hardware.

I would also try another USB port but contact Corsair if you need help.
