Hi,

Please phrase your question with proper interpunction and capitals. Long sentences without interpunction are hard to read.

Also it might be helpful if you describe what you have tried to fix the problem.

I did manage to get mine to work. You need to insert a null-modem cable between the USB-serial converter and the box.

Try the first link below, that is how I got my Interface B to work... so much that I went ahead and bought a second one with loads of sensors and the old 9V motors.

You should also search for RoboLab (available off the net) and install it, you'll have fun once it's up and running. Also, and unlike the Mndstorms sets, Interface B can interface with 16 transducers/sensors ... Now you can do a LOT with that.

what is a null modem cable?

Look it up on Wikipedia. It's a cable to connect two serial ports to one another, and you can get it from any computer store. Worst case, you can buy 2 DB9 connectors and wire them up yourself. Amazing how much has changed over the past few years.
