Thanks. You can ignore my other message about this. I should really
read all mails before answering :-)

I just checked the diff. Not counting the warnings, there are only two
things that changed between these two versions: The test for struct
semun in sem.h and the test for GPHOTO2. As GPHOTO2 is diabled by
default and sem.h is only used in snapscan, I don't understand what's
happening here. All the other changes are documentation related.

Are you sure that this isn't just a configuration problem? Can you
look with "SANE_DEBUG_EPSON=255 scanimage -L" what's happening? If
it's SCSI-related, you can also add "SANE_DEBUG_SANEI_SCSI=255".

Bye,
