sashatronics 2 Posted March 25, 2007 yes, after reading all the talk about how USB port workin poorly with issues on MAC's or other mashines, i gave it a try and drove few dozen miles to pick me up this $40 gadget, and use instead the one copam comes with. I hooked it up, and had no trouble on any cuts i made so far, cuts, draws..PERFECT, and working like it should work. I think thats the #1 problem on here with people asking questions. I say if you use USB port, and using COPAM model, to work for your ploter properly, you need to get KEYSPAN USA-19HS .. :USA: Share this post Link to post Share on other sites
