Dear sir,accordding to your description,there could be something wrong with communications between 6022BE and the PC USB port.Unplug the USB lead from 6022BE and the PC,and replug it into them.Make sure to plug the lead steadily.Windows is expected to find a new hardware is attached.If it doesnot work,change another PC to test or change a USB lead to examine.
