I thought it was going to work for us as a few machines I tested on it seemed to work. However the scanner will randomly stop working and it will say scanner is disconnected. Rebooting the computer usually fixes it so it will work again, but users don't like to have to keep closing out all their work just to fix a scanner.
We have had problems with the hp scanners from the time we bought them where the scanner itself would quit responding and after a few power cycles it might start working again. After that was discovered we have slowly been replacing all the scanners with Epson scanners and have not had any trouble with them.
We are just replacing our hp scanners now so we don't have to keep dealing with this waiting for microsoft or hp to fix it.
