Is the computer a laptop? The LiDE 400 requries power from the computer to which it is connected, along the USB cord. When a laptop is running off of battery power, the power along the USB cord will be reduced or limited, and the signal strength will be lower. To correct this type of problem, ensure the laptop's power adapter is plugged in and the laptop is charging.
If the problem occurs even when plugged in, or if the computer is a desktop computer, ensure the USB port in use is a USB 1 or 2 port. Some USB 3 ports experience issues with backwards compatibility. Also, double-check that the computer's security software and firewall are not blocking communications between the scanner and the computer.
