OMG !
I will test further, but thought the issue was with PinballX, but I disabled all my plugins and now the device is working ....
So hold off @Tom Speirsto check code. Need to check which plugin this is causing it
EDIT : Ok, an apology from my site to @Tom Speirs is needed. The strange behavior is caused by "DirecectOutput Pinball X" plugin. Disabling this plugin, makes the device working as it should be (but now I don't have the nice flashes/lights and effects)
Sorry Tom to put extra work to you. Never realized it could be a plugin ....
