I have a HP Photosmart C4240 All-in-One printer. When I try to scan something it states that the USB is not connected. Everything is plugged in and it use to work. Any suggestions?

Try plugging the USB into a different port on your computer.
Try it in another computer.
Try a different USB cable.

Uninstall the unit from Start, control panel, Add Remove Programs.
Turn off computer.
Start computer, place driver disk in drive.
See if the computer will recognizes it and sets it up again....

Printer and copier work fine- scanner says USB not connected.

I had this same problem and it is fixable, but not the way you would probably like, though you can still scan with the printer. You just have to open the Paint program and click from scanner or camera, and then choose your printer and click scan preview, and then scan, it works just fine but its a little time consuming.

This is a HP hardware/software error and HP has not fixed it.

The C4250 may report that "USB is not connected" but the printer works just fine and when you use the Microsoft Scanner and Camera Wizard to carry out a scan, it works just fine too. So the error message is wrong.

The Microsost Scanner and Camera Wizard can be found on the Control Panel.

Forget the scanning software form HP. This solution below works! At least untill HP do something to solve this. Windows Vista offers a built-in feature, named Windows Photo Gallery, that allows for scanning without using any imaging software. Follow these steps to scan with Windows Photo Gallery.
  1. Make sure that the product is on and that the USB cable is connected correctly.
  2. On the Windows taskbar, click the Windows icon (c01319360.gif ), click Programs , and then click Windows Photo Gallery .
  3. In the Windows Photo Gallery screen, click File and then click Import from Scanner or Camera .
  4. Look for an icon that represents the product.
    • If no icon appears on the screen, go to Solution five: Fully uninstall and reinstall the HP software.
    • If the icon does appear, click the icon and then click Import .
  5. Make any necessary changes to the settings on the Import screen and then click Preview .
  6. If the preview of the scan looks correct, click Scan . The scanned image imports into Windows Photo Gallery.
    • If the scan was successful, use the Windows Photo Gallery wizard to scan instead of using the HP software. To use the HP software, continue to the next solution to continue troubleshooting. However, it is not necessary to do so.
