Sorry, it took a while, but I have done it: I made log during scanning
with winstone (some programms had some problems with xp). I have
uploaded the log file of an 75dpi scan to this location:


This file was generated by "SniffUSB-x86-2.0.0006".

I hope this can help......

So Stef, if there is a new version of sane-backend, then I will test it

Kind regaards
