I connected the USB cable, but I am having problems using the HP All-in-One with my
computer
Cause The USB cable was connected before the software was installed. Connecting the
USB cable before prompted can cause errors.
Solution You must first install the software that came with the HP All-in-One before
connecting the USB cable. During installation, do not plug in the USB cable until prompted
by the onscreen instructions.
Once you have installed the software, connecting your computer to the HP All-in-One with a
USB cable is straightforward. Simply plug one end of the USB cable into the back of your
computer and the other into the back of the HP All-in-One. You can connect to any USB
port on the back of your computer.
For more information on installing the software and connecting the USB cable, see the
Setup Guide that came with the HP All-in-One.
