[sane-devel] Big problem with fi-5650c under linux

Fri Apr 13 15:52:44 UTC 2007

the sane 1.0.18-X comes from your linux distro, which i assume to be
suse? you cannot get the -X part from us. you could attempt to extract
it from their source package, but i dont think you need to, because:

you have spectacular liming. thanks to some help from Juan Pablo
Mendoza, i have just committed some code to sane cvs that should make
your scanner work on both scsi and usb, in all color modes. can you
please do a cvs checkout, verify that it contains fujitsu backend v
1.0.47, and make some tests with it?

i am especially interested in the line-shifting problem, and would
like to see a small sample, as well as a noisier debug log if the
problem continues with latest backend.
