I have no idea weather this is from the stone-age or not, but I got told to try a scanner out while clearing the girlfriend's loft (attic) out, and i cant find any vista/7 drivers for it anywhere.
MAKE - TRUST
MODEL - DIRECT WEBSCAN 19200
this is a pureUSB device (usb connected AND usb powered).
EDIT: downloaded the only avalable driver (named 12389_07.exe), run it, and it placed the following files into C:\download\driver\12389_XP
Web.W03~Web.W10 (see screen print)
Web.EXE will not excecute in Windows 7 (throwing an incompatibility error (version of this file is NOT compatible with your vesion of windows)), leaving me to believe its a 16-bit app.
