Here's what happens sometimes. When I power on, first all LEDs will light, then it will go through a sort of startup sequence. The ADC light will go on, the idle light will blink four times, and then the inhibit light goes on. Everything freezes, then I get it out of this state by putting the data line to ground. Then the busy/transmitting light will light, but with the scope I really don't see any data being transmitted, and when I connect this to the computer (through a USB adapter), no movement occurs. I've got to play with it some more to try to duplicate this behavior. Honestly, I can't take this anymore. I've been messing with this for quite a while as you guys know, and I'm running out of time. If someone could get this working, I would seriously pay them. :cry:
