If I set debounce time to 0ms for I2 (with my app developed in Lazarus) then counter starts counting "air" (board is free from external connections)- it not stops even I shortening I2 input with Inp1 button. Can You test this with Your board?

The control byte, set to a fixed $05 in the C++ demo program, appears to be sensitive to other values. I'm considering approaching Velleman to ask if they have documentation with the (mild) threat that I'll load the app onto Sourceforge or Berlios with the reset and debounce facilities disabled and a pop-up hint that they wouldn't tell me.

I can confirm the "counting-air" behaviour from last night. What's more something told the board to do something to the kernel (Linux 2.6.x) that subsequently prevented the board from initialising itself- that was only cured when I rebooted the computer. I don't think these boards have any USB-accessible non-volatile storage but I was obviously worried that I'd broken something.

In extremis I'll load the Velleman software onto one of our very few Windows computers and see if I can sniff the bus, I really don't like doing this since I don't want to risk fouling up a system used for e.g. PABX setup.
