Do this it worked for me..
Here is what you do. Remove the USB frm the HP and power on the unit.

Now begin a fresh re-install and you will re-connect the USB cable to the HP ONLY when the program asks you and NOT before.

Let it finish and REBOOT the computer.

Now go in the START menu and look in the HP folder and click on HP solution center. Put your document on the glass face down, select on the upper left, Scan pic and that's it.

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....

I have an hp c4240 all in one printer scanner and copier. I cannot get it to scan, it will copy and print fine though. It keeps telling me that the USB is not connected but it is. Do you know how I can fix...

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.
