Gimp suddenly doesn't see my scanner

[rich2005]

Quote:...snip...Random thought: might it work with a separate scanner program? Is there a handy/easy one?

Unlikely to work since you got: My device manager now calls the printer-scanner "Unknown Device"

Eventually it could still be a 32 / 64 bit problem The twain.exe plugin that comes with Gimp is 32 bit (even with 64 bit Gimp)

You could try IrfanView (32 bit version)
