(first, I apologize for the length of the post and my
poor english)
I'm trying to use a Microtek 600GS on a SPARCstation 1+
running Solaris 7. The installed 'Generic SCSI' is the
SCG driver by Klaus Schilling (aka SOLARIS_INTERFACE).
At first, the scanner was not recognized, it reports
"MII SC25 ScanMaker 600GS V4.6", and the microtek backend
only check for "SC {21,23,31}". Only find-scanner would
see it (trivial patch at the end of message, now it is
seen as a "600ZS").
Now, it is seen, but doesn't work.
First, there's a mis-feature inside the Solaris-SCG backend :
there's a seg-fault roaming line 2658 of
"sane-1.0.1/sanei/sanei_scsi.c" when DEBUG_LEVEL >= 3; the
DEBUG line try to printf() "*dst_size", which is sometimes
explicitly NULL.
Second, line 2688 of this file is :
2688: if (*(u_char *) & scmd.sense && handler)
When I try to "preview", "*(u_char *) & scmd.sense" is 0,
so the backend throw to an I/O error.
I've tried removing the check (maybe it's stupid ?), the result
is that the scanner start doing _something_ : the light move
from one side to the other, go back, then the software hang.
After a delay, I got SCSI error on the console :
####

Also,
"[sanei_scsi] sanei_scsi_cmd 8: timeout"
"[sanei_scsi] sanei_scsi_cmd 1b: timeout"
are send to stderr by xscanimage. Plus, an alert box with
"Error during read : Error during device I/O" shows up.
I still can quit xscanimage, but the scanner won't talk to
anybody until everything is power cycled, it seems.
If I "scan" instead of "preview", the result is almost the
same, that is, the back-and-forth move is replaced by
a window and the scanner seems to scan, but fails at the
end with the same SCSI error.
Note : when the light reached the end of the scanner, the
progress bar is only at around 5-10% of the total.
Here is the scanner inquiry:

Any idea on how to make that thing work ?
