Re: [Hp5400backend-devel] Trouble with Driver

[Thomas S. <sou...@ne...>]

Hi,

your problem is now that the version string sent by the scanner does not =
match=20
the ones we've got in development.

You have to modify the C code in hp5400.c to be able to run the backend.
The scanner is queried about a version string which is typically :
'SilitekIBlizd C3 ScannerV0.84' or 'SilitekIBlizd C3 ScannerV0.86' on the=
=20
scanner we tested.
You may disable this test, changing

  if( memcmp( szVersion+1, MatchVersion, sizeof(MatchVersion)-1 ) )
  {
    if( memcmp( szVersion+1, MatchVersion2, sizeof(MatchVersion2)-1 ) )
    {
      DBG(DBG_MSG, "Sorry, unknown scanner version. Attempted match on '%=
s'=20
and '%s'\n", MatchVersion, MatchVersion2 );
      DBG(DBG_MSG, "Vesion is '%s'", szVersion );
      ret =3D -1;
      goto hp5400_close_exit;
    }
  }

into :

#ifdef 0
  if( memcmp( szVersion+1, MatchVersion, sizeof(MatchVersion)-1 ) )
  {
    if( memcmp( szVersion+1, MatchVersion2, sizeof(MatchVersion2)-1 ) )
    {
      DBG(DBG_MSG, "Sorry, unknown scanner version. Attempted match on '%=
s'=20
and '%s'\n", MatchVersion, MatchVersion2 );
      DBG(DBG_MSG, "Vesion is '%s'", szVersion );
      ret =3D -1;
      goto hp5400_close_exit;
    }
  }
#endif

Note that you would be the first one to test it with your version of the=20
scanner. It should work but as the versions of the internal chipset are=20
different it may not.=20

Anyway I have added just now a similar patch in the CVS.=20
To disable the version test, look in the Makefile for NO_STRING_VERSION_M=
ATCH.


Thomas.
