A 'driver' in simple terms and pretty much exactly what it does: The driver is like a translation tool from one computer language to another (on the hardware, software and firmware levels). A driver, drives the communication process. So... if you do not have the correct drivers installed, your Legend and the computer will not speak to each other. On a whole other note sometimes the USB Root drivers installed on your computer (oodles and oodles of them) can become corrupted, or have not been updated, or incorrectly installed. As a previous computer tech, my first move is always to reboot the computer; ALWAYS! Sometimes the order in which 2 devices are (enumerated ie. counted in by the computer system) becomes key to success. In my thinking, it would be trying with detector on and then power up computer, so that the computer can Ack-N-Nack (enumerate, identify and connect with said detector). If this order does not work, then try the other way around too. OH' Ditto the the previous posts stating to follow the Nokta Legend Update directions in detail. Computers are so very very very unforgiving.
