If I plug in my USB Microsoft wireless mouse and USB Microsoft wireless keyboards at the same time, then the mouse and keyboards both become jittery. The mouse will stop moving smoothly and the keyboard will pause between key strokes. Initially I guessed this was signal interference with one-another, but it only happens after about 20 minutes of work (which is odd), and also only under Ubuntu.
Any ideas how this can be fixed? Are there alternative drivers that I can try?
