[sane-devel] a second try

[Dieter Jurzitza]

Dear Listmembers,
dear Mr. Meier - Geinitz,
dear Mr. Collins,
thanks for the hints. By the help of Martin Collin's and Henning 
Meier-Geinitz' inputs I probably found the issue:

Mr. Meier - Geinitz, yes, you are right, the code did not change. But this 
could be the problem.

The default value for the timeout related issues within this interface is 
derived from the HZ-value (?).

This changed from kernel 2.4 to 2.6, isn't it? Well ... I did what Martin 
suggested and the scanner worked by setting the environment-variable to ~300. 

In sanei_scsi.c / row 285:
static int sane_scsicmd_timeout = 120;

but then here:

#ifdef SG_SET_TIMEOUT
  /* Set large timeout since some scanners are slow but do not
     disconnect... ;-( */
  {
    int timeout;
    timeout = sane_scsicmd_timeout * HZ;
    ioctl (fd, SG_SET_TIMEOUT, &timeout);
  }
#endif

the HZ value is used here for actually configuring - I would really appreciate 
if someone could check. (But I did not find a place where SG_SET_TIMEOUT is 
set ...)

Many thanks for your efforts so far,
take care
