It's been a few years since I've asked for help but I need some now. I'm unable to get the K2 recognized by any computer program. So far the voltages have checked close until J2. Pin 1 is showing 2.3v and should be 0, pin 3 is showing 1v and should be 5v. J1 voltages are pretty close. The port is on, first thing I checked. Any ideas? Bob AA7EQ
