Not sure if your problem is the same as mine, but I encountered the same error and only to find that I plugged in a wrong power adapter so it didn't have enough power to advance the scanner head (My moving caused this mixup). Check your power adapter OUTPUT is 12V (or whatever is specified on the scanner itself, usually found on the label on the bottom or rear).

Thank you ever so much for the above solution. My Visioneer could not work with my VISTA but now after I followed the above procedure I have managed to perform my first scan.
Many thanks

I don't know what your electronics skill level is, but if you feel up to it, try taking the scanner apart and using a jumper wire to close the circuit so that the scanner is permanently unlocked. At least on a scanner this old you do not need to worry about voiding any warranty...

SOURCE: vista driver for visioneer 4400 USB scanner

Here is what worked for me. I have 32 bit Windows Vista. I do not think that this will work on a 64 bit Vista, as I don't think that a 32 bit driver will work on the 64 bit Vista.

Go to this URL:

http://support.visioneer.com/products/4400/downloads.asp

And download the 4400.303110.exe file to your computer.

Next: Click on "Start Search", and paste in
"mshta.exe res://acprgwiz.dll/compatmode.hta" without the quotes.
This will start the "Program Compatibility Wizard"

NOTE: The "Start Search" will appear when you click on the round Windows button at the lower left hand side of your Windows Vista desktop. It's right under "All Programs". Just paste that command in that box.

Then, just follow through.
When prompted for the program to run, select
"I want to locate the program manually" and point to the driver setup file you want to execute, which will be the file that you just downloaded.

Under the page that says to "Select a compatibility mode for the program"

Choose: 'Microsoft Windows XP (Service Pack 2)'

You don't have to select anything on the "Select display settings for the program" page.

On the next page, select "Run this program as an administrator".

You should be all set to go. I did see one complaint about a missing dll file, but it worked anyway.

Many thanks go the the people who really contributed to this fix:

They posted a lot of good information on this Microsoft forum:
