Hey, I need a bit of help solving a problem of mine.

From time to time my keyboard becomes unresponsive. Nothing happens when keys are pressed for some time, and then after a bit everything just happens "at once".

I have only noticed it while playing games (CS:GO, Minecraft) but this is probably because I would ascribe it to lack of some kind when doing anything else.

The keyboard is a Logitech MK710 combo with a mouse that DOES NOT become unresponsive when the keyboard does, even though it's using the same usb connector.

I have not been able to find any similar problems on google and I'm not experienced in these kid of problems so I was hoping to get some pointers of where to look for the origin of the problem.

I'm using Ubuntu 14.04 and I have tried putting new batteries in the keyboard
