could you try to run scanimage with debug logs enabled with the following
commands in a shell:
scanimage -d genesys >scan.pnm 2>scan.log
Then send me the scan.log and also the few other pnm debug files that will be
created in the directory where you'll run scanimage. With these I will be
able to have an idea of what is going on.
BTW, is your model really a MD6228 ? MD5345, MD6228 and MD6471 have the same
UBS id, but may be they are slightly different. The model I have is a MD6471.
