I beginner, but the equipment bought not much time there is a red light, after a variety of information search and inquiry, found that there are currently roughly the following two ways:
(1) Reinstall the SDK program, this can be downloaded to the Leap Motion website, basic every installation will succeed, but this method seems very cumbersome.
(2) From the Start menu into the command line mode, that is, cmd, then enter: Startnet Leapservice, and then return to start the device, if it is not possible to use the first method.
Also, each time you want to unplug, right-click on the chart in the lower right corner, select "Pause Tracking" and then unplug. Everyone has any questions welcome criticism, what good method also hope that we can learn from each other, common progress!
