I have tried basically anything I can think of to get the controller to show up when you go to preferences on cameo when you are in pepakura viewer 3. No matter what I do I cannot get it to show up whether I install drivers reinstall viewer whatever else. I had just barely gotten it to start working on my computer before it update to windows 10 though I have a computer on windows 7 that I can use for this also and neither work. I'm pretty much at my wits end trying to figure this out. All I want to do is to use my expensive paper weight to cut pieces out again. I hope someone can help me...Thanks.
