Hi there,

I have a recent 6040 model, that I think is very similar. I was lucky enough to have it work just fine out of the box. I guess I was lucky!

One thing that it could be: I've heard that some newer pcs only have 3.3volt outputs on the parallel port, which is not quit enough to properly drive the BOB. This might make it false step on the input. My PC is quite old, so it may not have been a problem.

If you would like, I can make measurements on my working machine to compare... A sanity check really.

Hope this helps.

Cheers,
Jay
