I use freestyler

and my controller is a homemade oksidizer USB DMX512
My problem is, sometimes, then I bump into the controller or something, the lights die on me, so?
is their a way, that I can make it so, that if I unplug and plug the usb plug of the DMX controller back into the pc, that the lights will continue with their stuff, without going offline. and the same with if I power down my laser and power it on while the programs is running, then the thing is messedup, but If i take out the DMX cable from the laser and plug it back, then the laser continuous with it stuff
TO fix with problem, I have to unplug everything and power on power of everything until it works again, and I have to restart the program, that is not cool..in a live situation
