Does anyone know of a way to get an old Visioneer 5800 scanner that's supposed to work with nothing past Windows XP SP1 to work on Windows 7 64-bit? I don't care about all the bells and whistles, just the basic features. Is there any kind of generic TWAIN interface that can be used?
you can use VirtualBox with USB support and setup a virtual machine with 32-bit XP.
other than virtualization, there is no way to get this dinosaur working with Windows 7 x64.
