Hi Paul,
Since the old SANE I was using (that came with TAME) no longer works with the current USBRESMG.SYS, I tried this new build.
The good news is that scanimage -L detects my scanner successfully. (So does sane-find-scanner, actually, in spite of what the readme says.)
The bad news is that it only works when the executable resides in a directory called 'sane' (not necessarily off the root). Unfortunately, TAME/2 requires scanimage.exe to be in its own program directory, so I cannot use it from TAME/2.
