HP Scanjet 3400c.

This always worked when I used Windows 95, then Windows ME, but since I have started using Windows XP I have found it impossible to get this to work.

Have installed with original install CD, with latest HP XP specific drivers, have installed via setup.exe and through add hardware/device manager but when launching Precision Scan LTX I am told - 'Scanner not found' the scanner is properly plugged in via power and usb and is lit up ready to go. When getting info on it from the scanners/cameras folder in my comp I have: Status - Unavailable.

Occasionally windows gives me a pop up of a 'usb device malfunction' so I have tried using various cables but still the same result, so where am I going wrong? Does this sound like a genuine XP problem or a hardware problem?

You should unplug your scanner from the USB. Uninstall the scanner software that you find in Control Panel "Add and Remove". Then install the software that you download from the above site. Shut down, plug in the scanner and boot up. XP will find and install the proper drivers.
