How do I properly install the HP All-in-One software to avoid USB connection errors?

You must install the software before connecting the USB cable to your computer. If you connected the USB cable before being prompted by the software installation screen, disconnect the cable, uninstall any partially installed software, restart your computer, and then reinstall the software from the CD-ROM. Do not plug in the USB cable until the software installation screen prompts you to do so. (Page 9)
