I have just comitted the following change to CVS: the USB part is now
in sanei_usb_attach_matching_devices so sanei_config2 now only depends
on sanei_scsi.

However, the following backends still have unmatched functions (try
nm backend/.libs/libsane-backend.so|grep "U sane"):

as6e: Is linked against sanei_config2 but not sanei_scsi
mustek_pp: Is linked against sanei_config2 but not sanei_scsi
umax_pp: Is linked against sanei_config2 but not sanei_scsi

Looks like these can be fixed by simply removing the reference to
sanei_config2 in backend/Makefile.in?

By the way: umax_pp also exports a symbol without sanei_ in its name.
Please fix (see make libcheck).

plustek: Is linked against sanei_config2 but not sanei_scsi

plustek.c really uses sanei_config_attach_matching_devices but if it
doesn't use SCSI this could be removed (or add sanei_scsi to the
Makefile). I don't know why this works at all.

st400: Doesn't link to sanei_scsi, sanei_config2 and
       sanei_constrain_value. As this was a simple spelling mistake
       in the Makefile.in I have changed this in CVS.
