Yes, I have one. I have some code also, tried to set up registers
based on Windows USB snoop logs (which I could not interpret easily),
but initialization does not yet work. Replaying the Windows commands
to the scanner does work though."



One more note ... I forgot to mention, that we would be happy even

for a minimal support. If you're able to scan anything with replaying

an unknown sequence representing let say a color scanning with

resolution 1200 DPI and lower contrast, it would be a very good start.

We can post-process the result in image editors.



"I intend to start again, using the latest GL841 code as a basis.

If you have sniffed data from several different tries with different
configuration, I could possibly look at them too and help with the
identification.  Depends on you.

Thanks,
Jaromir.
