hi have probably been up a thousand times before. But I do not get it to work. I can read the bus data from peak view but it finds no hardware in the zebra monitor. I installed the driver from the zebra file i downloaded which was 3.x. which I run on windows xp. have tried windows 7 also. Read that it is 2.x that seems to work best. Are they someone who can have that driver. Or are they something else I do wrong
