     ahem, in fact I realize I forgot to mail that a new version with 
early gl845 support was released. So you didn't miss anything.

     The cause of the problem is:

[genesys] genesys_send_shading_coefficient start
[genesys] genesys_send_shading_coefficient: sensor 26 not supported
[genesys] genesys_start_scan: failed to send shading calibration 
coefficients: Operation not supported
[genesys] sane_genesys_start: Operation not supported

I have still some places to change for this new sensor. Slope table 
traces also look bad. I think I can fix this this week.
