Check the both cable end connectors: the one to be connected to the machine and the other, to the computer.
The flat shaped connector: Connect to the USB port of the computer.
The square shaped connector: Connect to the USB port of the machine.
Change the USB cable. If you are using a long USB cable, replace it with a short one.
If you are using a USB hub, connect the machine directly to your computer using a USB cable.
Is the USB port disabled?
