Thanks. 

Your patch doesn't compile here with latest CVS:

sanei_pa4s2.c: In function sanei_pa4s2_get_status':
sanei_pa4s2.c:984: error: structure has no member named base'
[...]

Looks like you assume that libieee1284 is not present, but it is on my
system. Please check if you can use libiee1284 if available or at
least use some #ifdefs to get it compiled in both cases.

When I remove libieee1284 from my system I can compile the code but
get the following when trying to scan:

scanimage -L
scanimage: relocation error: /usr/local/lib/sane/libsane-mustek.so.1: undefined symbol: sanei_pa4s2_open_scsi_pp 

Your code seems to be only compiled in when libieee1284 is avaliable
or ENABLE_PARPORT_DIRECTIO is set manually. To avoid linking errors if
both is not the case, please provide stubs for your functions. There
are already some for the other sanei_pa4s2 functions at the end of the
file.

Fine. So which status do you think is ok for this scanner (from
doc/descriptions.txt)?

Some scanners do linedistance correction in hardware. So if the image
is ok (no colored stripes), this may be one of them.

The structure of the code seems ok for me and if you can get the
problem with sanei_pa4s2.c and libieee1284 fixed, I'll commit the
patch to CVS.

Do you know if the 600 II ED is the same scanner and may also work?

I'll append the modified manpage, so you may have a look if it's
correct.

Bye,
