There isn't a list as such. > I want to add my new Epson Perfection 4990 Scanner (vendor 4b8 device > 12a). Assuming you already have the Epson version of !TWAIN, you need to alter !Boot.Resources.!TWAIN.!EpsonGT.!Install. Duplicate one of the line pairs that start 'Alias @USBDevice' and 'If "<USB$Device_*_*_*' and change each occurrence of '04B8_xxxx' with '04B8_012A'. If you aren't sure then email the !Install file to me and I'll edit it for you.
