Hi!

As an owner of the Primax USB 19200 I read trough
this mailing list... and my hopes faded away :)

I've installed the E3 driver v0.6 with sane 1.09
with the scanner_erik_2.4.17 patch on 2.4.19 kernel.

Steven Ellis wrote (http://schwarz.thueday.de/primax/0451.html):
"Plus I have now had confirmation that the driver 
supports the Primax 19200 USB scanner."

Does that mean its IDs are recognized, or its
really working? I'm wondering because I found now
solution for the double IN endpoint problem.

Maybe this is already known, but if anyone is interested 
I experimented a little and these are my results:

I've tried the IBM Ideascan 2000 driver in
the following combinations and all of them failed
(the init program of the driver reported a lot
of unexpected answers: code 84 and the scan
program did hang).

ep1   ep2   ep3
---------------
OUT   IN    %
OUT   %     IN
OUT   IN    INTR
OUT   INTR  IN

% means endpoint unused

I tried the same combinations using the E3 driver,
but "scanimage -L" always did a segfault. An 
strace showed this:

old_mmap(0x40291000, 1266688, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_FI
ONYMOUS, -1, 0) = 0x40291000
close(3)                                = 0
open("./viceo.conf", O_RDONLY)          = -1 ENOENT (No such file or d

ioctl(4, 0x47, 0xbfffdbd0)              = -1 ETIMEDOUT (Connection tim
--- SIGSEGV (Segmentation fault) ---
+++ killed by SIGSEGV +++

On a win98 installation I used USBsniff to trace
scanner initialization and preview scan, the results
show the only the OUT and the second IN endpoints
ared used in the whole log.

If someone is interested in the logs:
http://llando.homeunix.org/doc/19200/index.htm

Finally: It would be nice if someone can help with the 
segfault or other solutions for the 19200.

Well at least someone else has been having fun with this scanner - I thought I 
was the only one! :-(  All of the snipped above is pretty meaningless to me, 
but I do know that the patched kernel on both a Mandrake and a Debian box was 
unable to assign a driver to the scanner.  Eventually gave up on the project, 
leaving a win98 only box for the scanner.  If there is anything I can do to 
help please let me know, bearing in mind I am not a programmer!

yes ... and asking Steven for the name didn't really help, yet :-(

no, you aren't, but I simply asked Steven directly several times and got
nothing really helping ...

the same problem as I have, and forcing a driver also didn't help. I tried
with vanilla kernel and both patches mentioned by Steven Ellis.
