As discussed before on this mailing list, I tried to write an open
driver in order to replace epkowa but I fail and I will live far from
the scanner in few weeks so I can't continue.
To sum up what is known today:
- the protocol is more or less like the epjitsu.
- however the command headers are

Cannot attach results due to limitations of this service.
The maximum size is 100Ko for the attachment.
- compress your files and see if the size decreases enough
- host it with a webserver or ftp server

When that's done, autoreconf and ./configure again.
Hope this helps,
I done what you said and the compile runs. I get .la file like the epjitsu.
Thank to you and m. allan noah!

Any news regarding the use of epjistu to directly drive the v100? (w/out
iscan)
I copied/paste the epjitsu files and renamed them as epv100. I change
few things in files but currently I'm fighting with the compilation
process:
- File 'configure.in':

It is difficult to know which scanner commands are vital to proper
operation, without trying :)

There are enough commands
different from epjitsu that I dont know if it makes sense to try and
cram it into that backend, at least not without a re-write first.

I have created a new file based on the Esfw66.bin and used `chksum` on
it. The sum doesn't match the data sended after the firmware in the
logfile. The error comes probably from me. I found the code used for
the checksum in epjistu.c so

Esfw66.bin is really the firmware: it's the main block of data in the
init logfile (starting at line 54). The differences are:
- the 100 first bytes of the firmware are not sended.

Well, it does use the same status command as the epjitsu scanners, and
the two-byte command and status layout is the same, but the actual
commands are slightly different. When I have more time I will try to
extract the image.

At that point, I would investigate the epjitsu sane backend, as it
already supports an epson chipset which may be related to the one in
the V100.
epjitsu.conf.in explains that the driver needs a firmware called
'*.nal', often in a cab file. I

Depending on how your system is configured, the existing

/usr/local/bin/scanimage will prefer /usr/local/lib. So, you might
just need to call the right binary...

Hello,
I bought an Epson Perfection V100 Photo which works with the epkowa
driver (with gt-s600).
I don't find a recent mail on the mailing-list talking about writing a
free driver. So I plan to (try to) develop it to remove the licence
problem. I never done reverse engineering or wrote driver
