I was mistaken- I actually have traces of the DR-C125. I spent some
time last night trying to figure out the image data format. I have
made some headway.

Are you able to get a trace of your scanner on an old version of
windows using this tool: http://www.pcausa.com/Utilities/UsbSnoop/  If
so, I could compare to the earlier scanner.
