I had a problem where my mouse and keyboard would be choppy, the mouse pointer would work at 1-2 fps and the keyboard would keep missing letters as I was typing them. Since they were both USB I suspected there was a problem there immediately. Whenever I got this problem I would suspend the computer and start it again and the problem would be gone. The problem started appearing when I plugged the mouse and keyboard directly into the computer rather than the USB hub in the screen. I'm using a Logitech UltraX Flat and a Razer Lachesis, but I'm not sure if that matters.
